This abstract first appeared for US patent application 18808316 titled 'COMPOSITION AND FILMS COMPRISING POLYLACTIC ACID POLYMER AND COPOLYMER COMPRISING LONG CHAIN ALKYL MOIETY

Original Abstract Submitted

Compositions and films are described comprising a polylactic acid (PLA) polymer. The composition further comprises a copolymer comprising a long chain alkyl moiety. The copolymer further comprises a second moiety that is miscible in the polylactic acid polymer. In favored embodiments, the composition comprising the polylactic acid polymer and copolymer may be used to form a release layer of an adhesive article such as a pressure sensitive adhesive tape. The films may be a monolithic film or a film layer of a multilayer film. The release layer may be disposed upon a substrate layer. The substrate layer may also comprise polylactic acid polymer. The substrate layer may be coextruded with the release layer. In some favored embodiments, the film or film layer is oriented.
