Title:
IMPACT-MODIFIED COMPOSITIONS
Document Type and Number:
WIPO Patent Application WO2004000936
Kind Code:
A8
Abstract:
In one of its aspects the invention is directed to rubber modified thermoplastic resin compositions 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 said thermoplastic phase comprises structural units derived from at least one vinyl aromatic monomer, at least one monoethylenically unsaturated nitrile monomer and at least one (C1-C12)alkyl- or aryl(meth)acrylate monomer. In another aspect the rigid thermoplastic phase of said compositions comprises a first thermoplastic phase at least a portion of which is grafted to the elastomeric phase; and a second thermoplastic phase prepared separately in the absence of elastomeric phase and added to the composition, wherein said first thermoplastic phase comprises structural units derived from at least one vinyl aromatic monomer, at least one monoethylenically unsaturated nitrile monomer and at least one (C1-C12)alkyl- or aryl-(meth)acrylate monomer; and wherein said second thermoplastic phase comprises structural units derived from at least one vinyl aromatic monomer and at least one monoethylenically unsaturated nitrile monomer.
