摘要： Graft-copolymers for improving impact strength comprising a relatively large quantity of an elastomeric trunk polymer, such as acrylonitrile/styrene/butadiene resins and methyl methacrylate/styrene/butadiene resins, have some undesirable powder characteristics, for example, poor fluidity and an easily blocking property.However, by blending a graft-copolymer of this type with a graft-copolymer comprising a relatively small quantity of an elastomeric trunk polymer in slurry form or dry state, it is possible to obtain a graft-copolymer blend with improved powder characteristics without significantly lowering the effect of improving the impact strength of the former graft-copolymer.The graft-copolymer blend thus obtained, when blended with a hard resin such as polyvinyl chloride, provides a resin composition with high impact strength.

摘要： A latex of a highly crosslinked butadiene rubber polymer comprising not less than 50% of butadiene, 1.0 to 10% of a crosslinking agent and a remainder of an ethylenically unsaturated monomer copolymerizable with butadiene, and having a particle size of 600 to 3,000 .ANG. and a degree of swelling of not greater than 7 is obtained by one or more stages of emulsion polymerization. By polymerizing 15 to 30 parts of a monomer mixture of an alkyl methacrylate, an aromatic vinyl monomer, and optionally a crosslinking agent and an unsaturated nitrile in the presence of 85 to 70 parts of the rubber polymer, a graft copolymer is obtained. A composition comprising 2 to 40% of this graft copolymer and 98 to 60% of a vinyl chloride resin possesses high impact resistance coupled with improved stress-whitening resistance, which properties cannot be easily obtained at the same time in conventional resin compositions.

摘要： A process for producing a graft-polymer comprises adding an aqueous solution of a salt of a strong acid and a monovalent strong base, which solution has been adjusted to a pH value of 8 to 13, to a rubber latex containing diene rubber particles and a fatty acid soap as an emulsifying agent to coagulate the above mentioned rubber particles, and thereafter adding a vinyl monomer to the latex containing the coagulated rubber particles to graft-polymerize the vinyl monomer.According to this process, the formation of rubber masses and macroparticles during the coagulation is reduced and a rubber latex containing rubber particles having a narrow range of particle size distribution is obtained. When a graft-copolymer obtained by using the latex is blended with thermoplastic resins such as vinyl chloride resins, the impact resistance of the thermoplastic resins can be remarkably improved without impairing their transparency and gloss.
