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 be evaluated from the observed cloud point curves. With a simple approach based on the mean-field theory for blends of a homopolymer with a random copolymer, the miscibility boundary could be determined as a function of composition of the copolymer. The predicted miscibility region for the given polymer pairs was compatible with the experimental results.
