| titleOfInvention | Improvements in or relating to the manufacture of synthetic rubber compositions |
| abstract | Moulding materials are made by forming a graft copolymer by reacting a mixture of 95-60% of a styrene and 5-40% of acrylonitrile with a synthetic rubber latex of polybutadiene or a copolymer of butadiene and styrene and/or acrylonitrile, 90-30 parts of monomer mixture being used per 10-70 parts of latex solids, coagulating and drying the graft polymer so produced and blending it with a particulate copolymer of acrylonitrile and a styrene containing 90-60% of the latter which has an intrinsic viscosity of less than 1 and has been prepared by suspension polymerization in the presence of an initiator and a chain transfer agent. The examples describe: (1) (a) grafting styrene and acrylonitrile in a polybutadiene latex in the presence of lauryl mercaptan, p-menthane hydroperoxide, ferrous sulphate and water, (b) copolymerizing styrene and acrylonitrile in aqueous suspension in the presence of a mixture of lauryl peroxide ditertiary butyl peroxide and diisopropyl percarbonate as initiator and a mixture of 1,4-dihydronaphthalene, alpha-methylstyrene dimer and dodecyl mercaptan as chain transfer agent, and (c) blending polymers (a) and (b); (3) as in (1) but using a styrene-acrylonitrile copolymer made in the presence of a mixture of lauryl, tertiary butyl and ditertiary butyl peroxides as initiator and a mixture of 1,4-dihydronaphthalene, dodecyl mercaptan and 1,1-diphenylethylene as chain transfer agent, and (5) the preparation of an acrylonitrile-styrene-alpha-methylstyrene copolymer in aqueous suspension in the presence of a mixture of lauryl, tert.-butyl and ditert.-butyl peroxides as initiator and a mixture of 1,4-dihydronaphthalene, dodecyl mercaptan and 1,1-diphenylethylene as a chain transfer agent. |
