Release film formed from polylactic acid-containing resin

摘要

Polylactic acid-containing resin composition that includes a polylactic acid; and a (meth)acryl-silicone copolymer that includes a methyl(meth)acrylate; and a reactive silicone, wherein the (meth)acryl-silicone copolymer has a weight average molecular weight of 25,000 or more. Methods for producing a polylactic acid-containing resin composition, polylactic acid-containing resin films, polylactic acid-containing resin release films, polylactic acid-containing resin release films, and methods for producing polylactic acid-containing resin films are also disclosed.

1. A method for producing a polylactic acid-containing resin composition,
producing a (meth)acryl-silicone copolymer from (i) methyl (meth)acrylate and (ii) a reactive silicone having a reactive group selected from a (meth)acryloyl group or a mercapto group, wherein the (meth)acryl-silicone copolymer has a weight average molecular weight of 25,000 or more and wherein the (meth)acryl-silicone copolymer comprises 10 to less than 50 weight percent of the silicone, mixing a polylactic acid and the (meth)acryl-silicone copolymer to form the polylactic acid-containing resin composition, wherein the weight ratio between the polylactic acid and the (meth)acryl-silicone copolymer is 99:1 to 50:50.
