4Skill-set needed Knowledgeable (content related) – general vs specific Digital literacyMulti-tasking abilityCommunication skillInter-personal skillProblem-solving skill
5Diverse industry needs Paints and coatingsAdhesivesSealantsIndustrial rubber productsDipped-goods: rubber gloves, balloonsMedical devicesTyres and inner tubesPolymer resinsFabrication of plastics productsOne of the biggest employers in Malaysia20% of the industries
6Issues Contents: knowledge imparted ► general vs specific practical skill in laboratoryCommunication skill: oral presentation, negotiationWriting skill: reports, manuscriptsUnderstanding power (language): readingInterpretation and deduction skillsAbility to conduct independent work
7What is lacking: employers view Need extensive on-the-job training in order to perform.The graduates require detailed explanation to understand specific subject matters and to carry out task.Innovation and thinking skill appear to be lacking. They lack ability to carry out their task independentlyMost need help in interpretation of results of analysis, and need specific direction and hand-holding in their job.
8University training Polymer as a degree programme Polymer only part of a chemistry degree programmeSome polymer modules are embedded in Materials science, Materials engineering, Chemical engineering, Nanotechnology programmesPolymer processing (non-chemistry, more technology)
9Training requirement differs Programme offered differs from University to university ►niche areaCourse contents differ: core vs electiveDuration differs (3 years vs 4 years)Credit hours required to pass differsWith/without industrial internshipWith/without laboratory training modulesWith/without minor research project
10Contents coverage Polymer synthesis Characterization Properties ApplicationsProcessingEnvironmental issuesDisposal methodsCurrent situation of the syllabus of polymer science in some universitiesPolymer chemistry is not compulsoryPolymer processing is not part of compulsory polymer contentThe content of latex technology is not sufficient.

12The proposal for the syllabus of polymer science for chemistry major and chemistry-related programs 2 courses with 3 credit hoursEach course: 2 hrs lecture per week + 3 hrs lab session per weekLab must be related to the theory70 contact hrs per course (28 hrs lecture + 42 hrs lab)IntroductionDefinition, classification, naming (IUPAC & non IUPAC, trade name), MWSynthesisAddition (free radical, ionic, ring-opening)Step-growth/condensation polymerizationCo-polymerizationKineticsMWDTechniques (bulk, solution, emulsion, suspension, dispersion)
15Laboratory training Recommendations: should be designed to impart skill on handling simple analytical apparatus (e.g. hands-on for viscometer, dilatometer, osmometer etc.).Statistical concept on data handing and analysis (reproducibility, repeatability, precision and accuracy) is emphasized.The introduction of instrument should be as basic as possible to allow self assembling capability.There should be at least ONE experiment that requires the undergraduates to partially design their own experiment, rather than provide detailed step by step procedure.
16Exp 1: Solubility and identification of polymers Objective: Solubility of macromolecules in low-molecular (mostly organic) solvents in addition of some IR test for identification of polymersDescription:The experiment will mediate experience in preparation of polymer solutions and qualitative evaluation of solubility and FTIR spectroscopy.FTIR tables will be provided.By comparing solubility of polymers in various solvents plus referring to FTIR analyses, the student could identify the polymers.
17Exp 2: Separation and purification of polymer Objectives:To carry out separation and purification of polymer.To perform quantitative analysis of PMMA and cinnamic acid by UV analysis.Description:PMMA is dissolved in chloroform containing added cinnamic acid as an”impurity”.The PMMA could be precipitated out from the chloroform solution by the addition of methanol.The precipitated PMMA could be isolated by filtration.Higher purification could be achieved through re-precipitation process.The removal of cinnamic acid could be confirmed with UV spectroscopic analysis.
18Exp 3: Preparation of polyester by condensation polymerization Objectives:Understanding the concept of synthesis polyester from the condensation polymerizationDetermining initial amounts of –OH and –COOH in the starting materials, ratio = [-COOH]/[-OH] and an average of molecular weight of polyester.Application of the Carothers EquationDescription:To prepare polyester by condensation polymerization of ethylene glycol (a diol) and phthalic anhydride (a dicarboxylic acid).The extend of reaction is monitored from the amount of water evolved from the condensation reaction.The average degree of polymerization is estimated by applying the Carothers Equation.
19Exp 4: Viscosity-average molecular weight Objectives:To determine the intrinsic viscosity of polystyrene sample in toluene solution.Determining the viscosity average molecular weight by applying the Mark-Houwink equation.Description:Measurements of the viscosity of dilute polymer solution using Ubberlohde viscometer.
20Exp 5: Determination of Mn by vapor pressure osmometer Objective:To determine the Mn by vapor pressure osmometer polymer sample in toluene solution.Description:The pure solvent and the polymer solution are separated by a semi-permeable membrane in vapor pressure (or membrane) osmometry.The hydrostatic excess pressure is measured in dependence on the polymer concentration of the solution.
21Exp 6: Determination of glass transition temperature by dilatometry technique Objective:Determination of glass transition temperature of poly (isobutyl methacrylate).Description:Tg of poly (isobutyl methacrylate) will be determined with dilatometry technique, i.e. by observing the change in height of the meniscus of the capillary tube / specific volume (which is related to the thermal expansion coefficient) of the polymer over a certain temperature range.
22Exp 7: Determination of the crosslink parameters of a vulcanised natural rubber Objectives:Understand the behaviour of the vulcanized natural rubber.To correlate the degree of vulcanisation from Mc the molecular weight between crosslink, by applying the Mooney-Rivlin equation at low extension ( < 1.5).Understand the concept of swelling of vulcanized rubber in toluene, where higher amount of crosslinking would reduce the solvent swelling.The Mc can be estimated from the volume fraction of the rubber in the solvent swollen sample.Description:stress strain method, the effect of hysteresis is shown by plotting the weight L (kg) vs extension λ for both addition and removal of load.swelling method consists of two stepsDetermination of density of rubberDetermination of the swelling of the rubber sample.
23Each student is assigned one mini project To be completed within 7 weeks.Each project consists of the following elements.Sample preparation(s) or sample treatment(s).Sample characterization by spectoscopic and/or thermal analysis.Data interpretation.
