✦ Synopsis

A~traet--The glass transition temperature of poly(4-hydroxystyrene) with poly(vinylacetate), poly-(methylmethacrylate) and various poly(acrylates) have been obtained over the whole composition range. The effect of the size of the side-chain group upon the miscibility has been found to be important, leading to partial miscibility for the blends with poly(n-butylacrylate) and poly(methylmethacrylate). On the other hand, the solvent from which the blend is cast has a noticeable effect on the composition dependence of the glass transition temperatures. Finally, the composition dependence of the glass transition temperatures of miscible blends has been correlated in terms of some lattice models.
