VISCOELASTIC PROPERTIES OF STYRENE – ACENAPHTHYLENE COPOLYMERS IN THE TRANSITION REGION

摘要

A series of styrene-acenaphthylene copolymers was prepared by thermal polymerization. Homogeneous samples were obtained, except for those compositions where the initial concentration of styrene monomer was 40 to 60 mole per cent. Master curves and characteristic viscoelastic parameters were obtained for the homogeneous copolymers. The plot of Tg versus copolymer composition yielded a linear relationship.
