Vinyl polymerization. XI. Binary systems of poly (methyl methacrylate)/and poly (ethyl methacrylate)/solvdnt by phase separation

Abstract

The thermodynamic interaction parameters of the systems, poly (ethyl methacrylate) /n-butanol and poly (methyl methacrylate) /n-butyl bromide and poly (methyl methacrylate)/isoamyl acetate were determined by methods involving phase separation and compared critically with values obtained by other methods. The validity of some of the well-known theoretical equations in the region of phase separation is considered.
