    摘要： Moulding compounds the ABS type consisting of at least one resin matrix and a particulate graft-rubber polymer distributed therein and produced by emulsion polymerisation, wherein at least 70% of the graft-rubber particles (number) exhibit a structure of the rubber phase which can be detected by photographs taken with the aid of a transmission electron microscope and in which the individual particles contain irregular cellular inclusions of resin-forming polymer and the surface of the particles exhibits an irregularly jagged structure such that, for each particle illustrated, 5 to 30 of such jagged projections are present which differ from an idealised round particle (with a diameter d) by virtue of a diameter d+d/x with x=3 to 15, as well as a process for the manufacture of said moulding compounds.

    摘要： A film-forming composition comprises from 0.1-8% by weight of an oligomeric polyglycidyl ether or ester and a polymer mixture ofa) a graft polymer prepared by polymerizing a monomer mixture of acrylonitrile, and alpha-methylstyrene and/or an alkylmethacrylate; or methylmethacrylate optionally with other monomers, onto cross-linked alkylacrylate rubber particles;b) a partially cross-linked rubber-like copolymer derived from an alkylacrylate and other monomers;c) an uncross-linked polymer of styrenes, (meth)acrylonitrile, (meth)acrylic acid esters and/or vinyl carboxylic acids; and optionallyd) a graft polymer obtained from the polymerization of a mixture of acrylonitrile, and styrenes and/or an alkylmethacrylate; or methylmethacrylate optionally with other monomers, onto cross-linked alkylacrylate rubber particles.
