Abstract
The dependence of miscibility on temperature for blends of poly(vinyl methyl ether) (PVME) and styrene-butadiene random copolymer (SBR) was studied. The binary interaction energy densities of the blends could b e evaluated from the observed cloud point curves. With a simple approa ch based on the mean-field theory for blends of a homopolymer with a r andom copolymer, the miscibility boundary could be determined as a fun ction of composition of the copolymer. The predicted miscibility regio n for the given polymer pairs was compatible with the experimental res ults. (C) 1997 Elsevier Science Ltd.
