INFLUENCE OF THE MOLECULAR WEIGHT OF POLYMETHYL METHACRYLATE ON THE MOLECULAR MOBILITY AND PHYSICOCHEMICAL PROPERTIES

摘要

The effect of molec.wt. on the molecular mobility, transition temperatures, relaxation and physicomechanical properties of PMMA was investigated. The data obtained revealed that it was possible to use PMMA with low molec.wts. as plasticisers and to produce bimodal systems or systems with specified MWDs possessing good processability and specified processing and service properties. 13 refs.
