Abstract
Phase separated articles that include a matrix phase including an acrylate copolymer; and a silicone elastomer phase stably dispersed in the matrix phase are described. The matrix phase may be derived from precursors comprising from 60 to 95 parts by weight of an alkyl acrylate having an alkyl group having 1 to 14 carbon atoms. Methods of forming phase separated articles, and articles including phase separated articles are also described.
Claims24
A phase separated article comprising:
- a matrix phase comprising an acrylate copolymer, the matrix phase derived from precursors comprising from 60 to 95 parts by weight of an alkyl acrylate having an alkyl group having 1 to 14 carbon atoms;
- and
- a silicone elastomer phase stably dispersed in the matrix phase.
A pressure sensitive adhesive article, the article comprising a copolymeric material, the copolymeric material comprising:
- a matrix phase comprising an acrylate copolymer, the matrix phase derived from precursors comprising from 60 to 95 parts by weight of an alkyl acrylate having an alkyl group having 1 to 14 carbon atoms;
- and
- a silicone elastomer phase stably dispersed in the matrix phase,
- wherein the copolymeric material is a pressure sensitive adhesive.
An optical article, the optical article comprising a copolymeric material, the copolymeric material comprising:
- a matrix phase comprising an acrylate copolymer, the matrix phase derived from precursors comprising from 60 to 95 parts by weight of an alkyl acrylate having an alkyl group having 1 to 14 carbon atoms;
- and
- a silicone elastomer phase stably dispersed in the matrix phase,
- wherein the copolymeric material is optically clear.
