ABSTRACT:
This invention relates to anionically polymerized block copolymers comprised of at least one block polyethylene and at least one block of a polymerized cyclic siloxane monomer, e.g., polydimethylsiloxane. Block copolymers with multiple "arms" may be formed by coupling these living diblocks with polyfunctional coupling agents. One copolymer for use in wax release coatings has an overall weight average molecular weight of 1500 to 100,000, a polyethylene block weight average molecular weight of less than 4100, and a polyethylene content of less than 55 percent by weight. Another copolymer for use in extruded release coating films prepared by blending the copolymer with a film grade polymer has an overall molecular weight of less than 20,000 and a polyethylene block molecular weight of less than 3700.
