ABSTRACT:
Iniferter prepared release coating compositions comprising vinyl-siloxane block copolymer and blends thereof with other polymeric materials on sheet materials and the backside of adhesive tapes are provided. Controlled and predictable release is obtained through variation of the molecular weight and weight percent of the siloxane block as well as the molecular weight and composition of the vinyl block or blocks.
