    摘要: The process for preparing copolymers of butyl acrylate and 1-(.alpha.-alkyl acrylate)-1-tert-butyl peroxy ethanes comprises performing emulsion copolymerization of butyl acrylate and 1-(.alpha.-alkyl acrylate)-1-tert-butyl peroxy ethanes in the presence of an initiating system consisting of sodium metabisulfite in an amount of 0.008 to 1.650% of the total mass of monomers and a compound of the general formula Na.sub.x H.sub.y S.sub.z O.sub.3, where "x" is an integer of 1 or 2, "y" is zero or 1, "z" is an integer of 1 or 2, said compound being in an amount of 0.002 to 0.360% of the total mass of monomers. In accordance to the required characteristics of the copolymers, i.e. extent of the final product swelling and the gel fraction content therein, the initiating system amount is determined from the formula: ##EQU1## c--amount of the initiating system, in % of the mass of initial monomers; .alpha.--extent of the final product swelling, in % of the final product mass;G--gel fraction content of the final product, in % of the final product mass.

    摘要: The process for producing shock-proof graft copolymers of styrene with synthetic rubber consists in that rubber is dissolved in styrene at a maximum temperature of 75.degree. C. The resultant solution is subjected to prepolymerization by being heated to 75-85.degree. C. in the presence of a plasticizer and a peroxide initiating agent. The peroxide initiator is essentially a composition of the following formulation (in parts by weight): diacylated peroxides of aliphatic acids C.sub.3 -C.sub.5, 2 to 8; diacylated peroxides of aliphatic acids C.sub.6 -C.sub.9, 80 to 89; diacylated peroxides of aliphatic acids C.sub.10 -C.sub.12, 7 to 14. The prepolymerization process proceeds until the 25-40 percent styrene conversion. The result is the prepolymer which is exposed to aqueous-suspension polymerization by being heated in an aqueous medium to maximum 140.degree. C. at a prepolymer-to-water volume ratio ranging within 5:3 and 10:3, respectively, in the presence of peroxide polymerization; initiators and a stabilizing system, consisting of 0.15-1.5 wt. % tricalcium phosphate, 0.003-0.02 wt. % of a mixture of disubstituted sodium alkylsulphates of a general formula as such: R--OSO.sub.3 Na, where R is a hydrocarbon radical, containing 8 to 18 carbon atoms, and 0.15-0.35 wt. % calcium carbonate.The process is distinguished for a simple flowsheet; it involves no molecular-weight modifier. Copolymers produced according to the proposed process feature high physico-mechanical characteristics.
