    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.
