| titleOfInvention | Copolymers of Acrylonitrile. |
| abstract | 1,185,308. Acrylonitrile terpolymers. IMPERIAL CHEMICAL INDUSTRIES Ltd. 29 Feb., 1968 [7 March, 1967; 20 Sept., 1967], Nos. 42897/67 and 42898/67. Divided out of 1,185,305. Headings C3G and C3P. A random copolymer comprises units of acrylonitrile and units of at least one aromatic olefin in a molar ratio of acrylonitrile to aromatic olefin of between 2 and 6 and contains up to 10 mole per cent (where the sum of acrylonitrile and aromatic olefin units represents 100 mole per cent) of copolymerized units of at least one monomer selected from maleimide and its N- substituted derivatives and norbornene and its derivatives, including methylene norbornane. The aromatic olefin is, e.g. styrene or a substituted styrene, acenaphthylene, indene, coumarone, 1-vinyl naphthalene, 2-vinyl thiophene, 3-vinyl phenanthrene, 2-methyl-5-vinyl pyridine or N-vinyl carbazole. Preferred maleimides are N-aryl maleimides, e.g. N-phenyl or N-o-chlorophenyl maleimide. The copolymer is used in blends with graft copolymers such as polybutadiene grafted with acrylonitrile and isobutene or styrene. The copolymer is prepared by a process in which at least the aromatic olefin is fed into the reaction medium as the polymerization proceeds, at a rate determined by the heat evolved by the polymerization. In the examples, terpolymers of acrylonitrile and styrene with N-o-chlorophenyl maleimide, 5- cyanonorbomene, maleimide or methylene norbornane are prepared, as are terpolymers of acrylonitrile and alpha-methyl styrene with N- o-chlorophenyl maleimide or maleimide, by polymerization in an aqueous medium. The acrylonitrile / styrene / N-o-chlorophenyl maleimide terpolymer is blended with a stabilized polybutadiene/acrylonitrile-isobutene graft copolymer, or polybutadiene / acrylonitrilestyrene graft copolymer and the acrylonitrile/ alpha-methyl styrene/N-o-chlorophenyl maleimide terpolymer is similarly blended. |
