Abstract
The present invention is concerned with thermoplastic molding materials of high molecular weight, thermoplastic, aromatic polycarbonates based on aromatic dihydroxy compounds and containing from about 0.01 to 0.1% by weight of esters of saturated aliphatic carboxylic acids with 10 to 20 C atoms and 4-hydric to 6-hydric alcohols.
Claims14
Thermoplastic molding materials comprising high molecular weight, thermoplastic, aromatic polycarbonates based on aromatic dihydroxy compounds and containing from about 0.01 to 0.1% by weight of esters of saturated aliphatic carboxylic acids with 10 to 20 C atoms and aliphatic 4-hydric to 6-hydric alcohols.
Thermoplastic molding materials according to claim12 wherein said partial esters contain not more than one unesterified OH-group.
