摘要：
The structural stare and segmental dynamics in amorphous miscible blends of polystyrene and poly(alpha-methyl styrene) were studied by DSC and mid- and far-IR spectroscopy (25-1700 cm(-1)). Considerable nonadditivity of the blend spectrum and some specific features of segmental dynamics, in particular, two sharply decreased glass transition temperatures in single-phase blends and two- or threefold reduction of the activation parameters of segmental motion, were disclosed, These effects were interpreted, and they can be predicted based on the concept of a common segmental nature of alpha- and beta-relaxations in chain-flexible polymers.
