Abstract
An acrylic elastomer copolymer that is a copolymer of (A) an alkyl (meth)acrylate and/or alkoxyalkyl (meth)acrylate monomer, (B) an α,β-unsaturated carboxylic acid monomer, and (C) a (meth)acrylate monomer having a carbamic acid ester group represented by the general formula: (wherein R1 is a hydrogen atom or a methyl group, and R2 is a divalent aliphatic hydrocarbon group having 1 to 10 carbon atoms). A crosslinkable composition in which a crosslinking accelerator is compounded with the acrylic elastomer copolymer.
Claims2
A crosslinkable composition comprising 0.1 to 5 parts by weight of a crosslinking accelerator, based on 100 parts by weight of an acrylic elastomer copolymer, wherein the acrylic elastomer copolymer is being a copolymer of:
- (A) 90 to 99.8 wt % of an alkyl (meth)acrylate and/or alkoxyalkyl (meth)acrylate monomer,
- (B) 0.1 to 5 wt % of an α,β-unsaturated carboxylic acid monomer, and
- (C) 0.1 to 5 wt % of a (meth)acrylate monomer having a carbamic acid ester group represented by the general formula:
- where
- R1 is a hydrogen atom or a methyl group, and
- R2 is a divalent aliphatic hydrocarbon group having 1 to 10 carbon atoms.
