MISCHUNGEN VON POLYCARBONATEN MIT SILOXANHALTIGEN PFROPFPOLYMERISATEN.

摘要

Thermoplastic polycarbonate moulding compsn. contains 52-94 (wt.)% polycarbonate(s) (I) and 6-48% particulate graft polymer(s) (II). The novelty is that (II) consists of 20-90 pts. grafted alpha,beta-unsatd. olefinic monomer(s) (III) on 80-10 pts. graft substrate (IV) with core/shell structure. The core consists of organic resinous polymer (V) of olefinically unsatd. monomers with Ig above 30 deg.C and the shell of crosslinked silicone rubber. The core/shell ratio is 0.1:99.9 to 90:10 and (II) has an average particle dia., d50 of 0.05-10 microns.
