    Abstract: 1,190,637. Impact-resistant styrene-acrylonitrile copolymers. BADISCHE ANILIN- & SODA-FABRIK A.G. 8 Sept., 1967 [10 Sept., 1966], No. 41116/67. Heading C3G. Impact-resistant styrene copolymers are produced by polymerization of styrene and acrylonitrile in the presence of a homopolymer and/or copolymer of butadiene, wherein at least 40% but less than 100% by weight of the acrylonitrile used is not added until after the homogeneous rubber-monomer phase has formed a disperse phase. The polymerization may be carried out in solution or in bulk, either entirely or until formation of the disperse phase, after which the polymerization may be completed in suspension in an aqueous medium. In the examples, (1) a solution of polybutadiene in styrene and acrylonitrile is polymerized to form a prepolymer, to which are added acrylonitrile and styrene before completion of polymerization in an aqueous medium, (4) a solution of a butadiene-styrene rubber, styrene and acrylonitrile is polymerized as in Example 1, (7) a solution of polybutadiene in styrene, acrylonitrile and ethyl benzene is polymerized continuously in a series of three vessels, acrylonitrile being pumped into the third vessel, (9) a solution of a stereospecific butadiene-styrene rubber in styrene, acrylonitrile and isopropylbenzene is polymerized continuously in a series of five reactors, additional acrylonitrile being supplied to reactors 2 and 3, and (11) the process of Example 9 is repeated, except that the rubber is polybutadiene.
