PHÂN TÍCH POLYME ( POLYME ANALYSIS )

Is a branch of polymer science dealing with analysis and characterisation of polymers. üThe complication of macromolecular chains, the dispersion in molecular weight, tacticity, crystallinity, orientation, composition of polymers etc. and complex morphological systems ⇒ analysis of polymer ≠ the small organic materials ⇒ Focus on viscoelastic properties, dynamic mechanical testing. Methods of polymer analysis Chemical, Molecular and Structural Characterisation -Molecular weight determination, -Microstructural characterisation and compositional analysis, -Crystallinity, -Investigation of polymer morphology, particle size, -Contact angle and wettability measurements Instruments FT-IR IR-microscope GPC ( size exclusion chromatography SEC) -Viscosimetry -X-ray (WAXS and SAXS) -EM, SEM, TEM, AFM -Dynamic and static methods...
