    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 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.

    摘要: A polyvinyl chloride resin composition comprises 3-30 wt. % of a graft copolymer and 97-70 wt. % of a polyvinyl chloride resin and has highly-balanced properties between impact resistance, transparency and stress-whitening resistance and excellent processing characteristics. The graft copolymer is obtained by graft-polymerizing, in the presence of a latex containing greater than 75 but not exceeding 85 parts by weight of a rubbery butadiene-styrene copolymer formed of 65-85 wt. % of butadiene, 15-35 wt. % of styrene and 0-3 wt. % of crosslinkable monomer, (i) 5-24 parts by weight of a first monomer mixture as a first-stage component, said first monomer mixture being composed of 70-97 wt. % of methyl methacrylate and 30-3 wt. % of an alkyl acrylate whose alkyl group has 1-8 carbon atoms; and then (ii) 3-21 parts by weight of a second monomer mixture as a second-stage component, said second monomer mixture being composed of 97-100 wt % of styrene and 0-3 wt. % of crosslinkable monomer. The sum of the first and second monomer mixtures and the rubbery butadiene-styrene copolymer is 100 parts by weight. The monomers grafted in the first stage amount to 30-80 wt. % of the sum of the grafted monomers.
