Abstract

Organopolysiloxanes having polyether and ester groups linked to a common spacer group, wherein the spacer group is linked through an SiC bond to the siloxane backbone and a method for the synthesis thereof are disclosed. These compounds are useful as additives for plastics, lacquers and binders for reducing the coefficient of sliding friction, for improving scratch resistance and increasing abhesiveness. If the compounds are esters of acrylic or methacrylic acid, they can be used as radiation-curable lacquers and coating compositions.
