Title (EN) COMPOSITION AND FILMS COMPRISING POLYLACTIC ACID POLYMER AND COPOLYMER COMPRISING LONG CHAIN ALKYL MOIETY
(FR) COMPOSITION ET FILMS COMPRENANT UN POLYMÈRE DE POLY(ACIDE LACTIQUE) ET COPOLYMÈRE COMPRENANT UNE FRACTION ALKYLE À LONGUE CHAÎNE
Abstract:
(EN) Compositions and films are described comprising a polylactic (PLA) polymer and a copolymer comprising a first moiety comprising a C12-C30 alkyl group and a second moiety that is miscible in the composition. Suitable first moieties include a C12-C30 alkyl (meth)acrylate or a polyvinyl alcohol comprising pendent C12-C30 alkyl groups. Suitable second moieties include C1-C10 (meth)acrylic acid or ester thereof, vinyl acetate and ethylene vinyl acetate. The aforementioned composition 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 that may also comprise PLA. The films are produced by melt extrusion of the aforementioned composition and may be oriented.
(FR) La présente invention concerne des compositions et des films comprenant un polymère de poly(acide lactique) (PLA) et un copolymère comprenant une première fraction comprenant un groupe alkyle en C12 à C30 et une seconde fraction qui est miscible dans la composition. Les premières fractions appropriées comprennent un (méth)acrylate d’alkyle en C12 à C30 ou un poly(alcool de vinyle) comprenant des groupes alkyle pendants en C12 à C30. De secondes fractions appropriées comprennent de l’acide (méth)acrylique en C1 à C10 ou son ester, de l’acétate de vinyle et de l’éthylène-acétate de vinyle. La composition susmentionnée peut être utilisée pour former une couche de décollement d’un article adhésif tel qu’une bande adhésive sensible à la pression. Les films peuvent être un film monolithique ou une couche de film d’un film multicouche. La couche de décollement peut être disposée sur une couche formant substrat qui peut également comprendre du PLA. Les films sont produits par extrusion à l’état fondu de la composition susmentionnée et peuvent être orientés.
