Claims
- 1. A curable resin composition comprising:
- (a) an acrylic copolymer having (i) an organohydrogenpolysiloxane macromonomer unit having a silicon-hydrogen bond and a 3-(meth)acryloyloxypropyl group attached to the silicon atom, (ii) an alkenyl group-containing acrylic monomer unit, and optionally (iii) an ethylenically unsaturated monomer unit, and
- (b) a catalytically effective amount of a hydrosilylation catalyst.
- 2. The curable resin composition of claim 1, wherein said macromonomer has an average composition of: ##STR24## wherein R is a C.sub.1 -C.sub.6 alkyl or phenyl, R' is hydrogen or methyl, a is a real number of from 0 to 20, b is a real number of from 0.5 to 3, and c is a real number of from 0 to 10.
- 3. The curable resin composition of claim 1, wherein said macromonomer has an average composition of: ##STR25## wherein R is a C.sub.1 -C.sub.6 alkyl or phenyl, R' is hydrogen or methyl, a is a real number of from 0 to 20, b is a real number of from 0.5 to 3 and d is a real number of from 1 to 10.
- 4. The curable resin composition of claim 1, wherein said macromonomer has an average composition of: ##STR26## wherein R is a C.sub.1 -C.sub.6 alkyl or phenyl, R' is hydrogen or methyl, R" is the same as R or a group --OSi(R).sub.2 H, R'" is hydrogen when R" is the same as R or otherwise a group --OSi(R).sub.2 H, and c is a real number of from 0 to 10.
- 5. The curable resin composition of claim 1, wherein said acrylic copolymer is produced by copolymerizing a monomeric composition comprising said macromonomer and said alkenyl group-containing monomer.
- 6. The curable resin composition of claim 4, wherein said alkenyl group-containing acrylic monomer is allyl (meth) acrylate, 2-butenyl (meth)acrylate, 3-methyl-3-butenyl (meth)acrylate, cyclohexenylmethyl (meth)acrylate, 2-methyl-2-propenyl (meth)acrylate, 3-heptenyl (meth)acrylate, 4-hexenyl (meth)acrylate, adduct of 2-hydroxyethyl methacrylate with vinylcyclohexene monoepoxide, or vinyl-terminated polydimethylsiloxypropyl (meth)acrylate.
- 7. The curable resin composition of claim 1, wherein said acrylic copolymer is produced by copolymerizing a monomeric composition comprising said macromonomer and an acrylic monomer having a carboxyl, glycidyl or isocyanato group, and then reacting the resulting copolymer with an alkenol or alkenoic acid.
- 8. The curable resin composition according to claim 1, wherein said hydrosilylation catalyst is a platinum compound.
- 9. The curable resin composition according to claim 1, wherein the proportions of said macromonomer unit and said alkenyl monomer unit in said copolymer is such that 0.4 to 4 atoms of the hydrogen atom attached to the silicon atom are present for each alkenyl group.
- 10. The curable resin composition according to claim 1, wherein said catalyst is present in said composition in an amount between 5 to 10,000 ppm relative to 100 parts by weight of solids of said composition.
- 11. The curable resin composition of claim 1, wherein the acrylic copolymer (a) is self-crosslinkable.
