    摘要: Novel addition polymers and copolymers derived from carbamate-functionalized vinyl monomers, and optionally one or more conventional vinyl monomers such as acrylonitrile and/or styrene, are disclosed. When the addition polymers or copolymers are melt processed with an elastomer containing moieties reactive with amines, novel addition polymer-rubber copolymers are formed which are useful as compatibilizers and impact modifiers in plastic blends, such as AES.

    摘要: Core-shell ABS copolymers having an SAN shell completely surrounding the diene core are provided by melt blending an aliphatic diene polymer with an SAN copolymer, said copolymer containing functional groups capable of reacting with the diene polymer. For example, the SAN copolymer may contain azide groups capable of reacting with the olefinic groups in the diene polymer, or both the SAN copolymer and the diene polymer may contain other functional groups capable of interreaction, such as acidic (e.g., maleic anhydride) groups in the diene and epoxy (e.g., glycidyl methacrylate) groups in the SAN copolymer.

    摘要: Copolymer compositions useful as impact modifiers are prepared by blending, under reactive conditions, at least one functionalized addition polymer with an excess of at least one functionalized elastomer reactive therewith to form a preblend, and subsequently blending said preblend, under reactive conditions, with a further amount of at least one functionalized addition polymer. The preferred addition polymers and elastomers are carbamate-functionalized styrene-acrylonitrile copolymers and maleic anhydride-grafted EPDM elastomers, respectively. The product of the two-step blending operation is a composition comprising a continuous addition polymer phase and elastomer particles dispersed therein, said elastomer particles containing occluded addition polymer. Said composition is stabilized by copolymer formation between the elastomer particles and the addition polymer.
