Abstract
The phase behaviours in binary blends of styrene-isoprene diblock copo lymer and poly(vinyl methyl ether) (PVME) were investigated by using s mall-angle X-ray and light scattering techniques. It was observed that the added homopolymer molecules were dissolved into the microdomains of the styrene blocks of the copolymer. The blends exhibited a lower c ritical solution temperature as seen in the blends of PVME with polyst yrene. The experimental results were compared with that of the modifie d Meier's theory in a semiquantitative way. (C) 1997 Elsevier Science Ltd.
