Abstract: A process which comprises reacting maleic anhydride and a primary or secondary C.sub.1 -C.sub.18 alcohol to form a maleic half ester, and then polymerizing the half ester and monoalkenyl aromatic monomer in ester solvent in the presence of a catalyst to form a solution of monoalkenyl aromatic monomer-maleic half ester copolymer having a weight average molecular weight of at least 110,000 Daltons. After formation of the copolymer, the reaction solution is neutralized to form a mixture of an alkaline salt solution of the copolymer and solvent and then the solvent is removed from the mixture.

Abstract: Terpolymers of styrene, mono-iso-butyl maleate and mono-2-(n-butoxy)ethyl maleate wherein the ratio of styrene units to maleate units is in the range of about 1:1 to about 1.6:1 and the ratio of mono-iso-butyl maleate units to mono-2-(n-butoxy)ethyl maleate is in the range of about 3:2 to about 1:3.

Abstract: Electrically conductive polymer blends of an acetylene polymer and an elastomer having a low level of unsaturation are disclosed herein. The low level of unsaturation provides resistance to heat, light, oxygen and ozone and yet provides sufficient sites for crosslinking of the blend to provide increased stability. These blends exhibit high conductivity upon doping with electron donors or electron acceptors.
