✦ Synopsis


Partitioning of low molecular weight species, such as oligomers, during melt blending is shown to contribute to relative shifts in recorded glass transition temperatures for immiscible blends of bisphenol-A polycarbonate and styrene/acrylonitrile copolymers. These observations indicate the problems in drawing conclusions about miscibility between two polymers solely from shifts of 'one-number' Tg values.

In this paper a new method based on the determination of heat capacity increment at the glass transition (⌬Cp) is presented to quantify the effectiveness of compatibilizers for immiscible polymer blends. In order to show the validity of the method, two immiscible blends, polypropylene-poly(ethylene

## Abstract Mixtures of high molecular weight polystyrene (__P__~n~ = 961.5; __T__~g~ = 373 K) and __sec‐__butyl‐terminated oligostyrene (__P__~n~ = 10.6; __T__~g~ = 302 K) show a dependence of the glass transition on the composition (i.e. number‐average molecular weight) which cannot be described
