(METH)ACRYLIC RESIN COMPOSITION, IMIDIZED (METH)ACRYLIC RESIN COMPOSITION, AND FILM OBTAINED BY MOLDING THEM |
摘要 |
<p>The present invention provides a (meth)acrylic resin composition comprising a carboxylic acid group produced by heating a (meth)acrylic-based resin (C), wherein the (meth)acrylic-based resin (C) is obtained by polymerizing a monomer mixture (A) containing 80 to 99 wt% of a linear alkyl (meth)acrylate and 1 to 20 wt% of tertiary-butyl (meth)acrylate, in the presence of an acrylic acid ester-based crosslinked elastic particle (B) that is obtained by mixing and polymerizing 0.5 to 5 parts by weight of a polyfunctional monomer having at least two non-conjugated double bonds per molecule, with respect to 100 parts by weight of a monomer mixture containing 50 to 100 wt% of an alkyl acrylate monomer and 0 to 50 wt% of an alkyl methacrylate monomer. This composition can be used to produce a film having excellent chemical resistance (in particular, sun-screening agent resistance).</p> |
