ABSTRACT:
Release coating compositions comprising polysiloxane-grafted copolymer and blends thereof with other polymeric materials on sheet materials and the back side of adhesive tapes are provided. Controlled and predictable release is achieved through variation of the number and the length, e.g., the molecular weight, of polysiloxane grafts in the copolymer.
