ABSTRACT:
Lacquers and molding compositions containing an anti-adhesive character producing and lubricity increasing amount of a polyester-containing polysiloxane corresponding to the formula ##STR1## wherein A, B and D each represent --CH.sub.3 or --Z--R--Q; Z represents an alkylene group with 1 to 11 carbon atoms, --(CH.sub.2).sub.2 SCH.sub.2 --or --(CH.sub.2).sub.3 NHCO--; R represents an aliphatic, cycloaliphatic or aromatic group containing at least 3 carboxylate ester groups and having an average molecular weight Mn of 300 to 3,000; Q represents a reactive group capable of chemically reacting with a resin component of the lacquer or molding composition; x represents a number from 4 to 150; y represents a number from 1 to 6, in which an average molecule contains at least one group --Z--R--Q and the ratio of the number of --Z--R--Q groups to the number x is from 1:3 to 1:30. A process for imparting anti-adhesive character and increasing lubricity of lacquers and molding compositions by incorporating such polyester-containing polysiloxanes into the compositions as additives is also disclosed.
