摘要:
Disclosed are compositions comprising: (i) a rubber modified thermoplastic resin comprising a discontinuous elastomeric phase dispersed in a rigid thermoplastic phase, wherein at least a portion of the rigid thermoplastic phase is grafted to the elastomeric phase, and wherein the elastomeric phase comprises a polymer having structural units derived from at least one (C1-C12)alkyl(meth)acrylate monomer; (ii) a second polymer consisting essentially of structural units derived from at least one (C1-C12)alkyl(meth)acrylate monomer; and optionally (iii) a third polymer comprising structural units derived from at least one alkenyl aromatic monomer and at least one monoethylenically unsaturated nitrile monomer prepared in a separate polymerization step and added to the composition. In other embodiments the present invention comprises articles made from said compositions.
