Abstract
1411839 Terpolymers POLYSAR Ltd 22 Nov 1973 [27 Nov 1972] 54227/73 Heading C3P A terpolymer of (a) 60-80% of CH 2 = CR-CN where R is H, C 1 -C 4 alkyl or halogen, (b) 5- 25% of CH 2 = CR<SP>1</SP>R<SP>2</SP> where R<SP>1</SP> is H, Cl or methyl and R<SP>2</SP> is phenyl optionally substituted with halogen or lower alkyl and (c) 5-25% of CH 2 = CR<SP>3</SP>R<SP>4</SP> (preferably isobutylene) where R<SP>3</SP> and R<SP>4</SP> are C 1 -C 4 alkyl is obtained by emulsifying at least part of (c), heating to 20-80‹C. and adding (a) and (b) simultaneously so that not more than 25% has been added before a significant amount of (e) has polymerized, the remainder being added in the ratio required in the polymer and in the range (a) : 16 ) of 13-2.5 : 1, the total amount of monomers being added after 60% but before 80% conversion and continuing to at least 85% conversion.
