(METH)ACRYLIC POLYMER, (METH)ACRYLIC RESIN COMPOSITION, (METH)ACRYLIC RESIN SHEET, (METH)ACRYLIC RESIN LAMINATED ARTICLE AND COMPOSITE SHEET

摘要

A (meth)acrylic polymer, a (meth)acrylic resin sheet containing same, a (meth)acrylic resin laminated article obtained by laminating a functional layer on one or both sides of a (meth)acrylic resin sheet, and a composite sheet containing said article. Said polymer contains 4.5-7.5% by mass of units of (a) an acrylate having a C1-11 hydrocarbon group and one ethylenically unsaturated bond in the molecule, 0.3-3.2% by mass of units of (b) a monomer having two or more ethylenically unsaturated bonds in the molecule, and 89.3-95.2% by mass of units of (c) a (meth)acrylate other than the monomer units.

1. A (meth)acrylic polymer (A) comprising:
4.5 to 7.5% by mass of a monomer (a) unit; 0.3 to 3.2% by mass of a monomer (b) unit; and 89.3 to 95.2% by mass of a monomer (c) unit,wherein
the monomer (a) unit is an acrylic acid ester unit having a hydrocarbon group with 1 to 11 carbon atoms and one ethylenically unsaturated bond in the molecule, the monomer (b) unit is a monomer unit having two or more ethylenically unsaturated bonds in the molecule, and the monomer (c) unit is a (meth)acrylic acid ester unit other than the monomer units.
