Abstract
The invention relates to a transparent masterbatch for improving the surface properties of thermoplastics, said masterbatch containing from 10% to 60% by weight of polyhedral oligomeric silicon-oxygen cluster units in accordance with the formula [(RX,SiO)(RXSIO)(RXSiO)(RXSiO)] where: a, b, c=0-1; d=1-2; e, f, g=0-3; h=1-4; m+n+o+p≧4; a+b=1; c+d=2; e+f=3 and g+h=4; R=hydrogen atom, alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl group or polymer unit, each substituted or unsubstituted, or further functionalized polyhedral oligomeric silicon-oxygen cluster units attached via a polymer unit or a bridging unit, X=oxy, hydroxy, alkoxy, carboxy, silyl, alkylsilyl, alkoxysilyl, siloxy, alkylsiloxy, alkoxysiloxy, silylalkyl, alkoxysilylalkyl, alkylsilylalkyl, halogen, epoxy, ester, fluoroalkyl, isocyanate, blocked isocyanate, acrylate, methacrylate, nitrile, amino, phosphine or polyether group or substituents of type R containing at least one such group of type X the substituents of type R being identical or different and the substituents of type X being identical or different and from 40% to 9011/o by weight of a thermoplastic carrier material, and to a transparent thermoplastic and to its production process.
