Claims
- 1. A core-shell copolymer comprising particles wherein the core comprises particles of a diene-maleic anhydride copolymer and the shell is a copolymer of an ethylenically unsaturated nitrile, an alkenylaromatic compound and glycidyl methacrylate, said shell completely surrounding and being chemically linked to said core particles.
- 2. A copolymer according to claim 1 wherein the core also comprises a copolymer of an ethylenically unsaturated nitrile and an alkenylaromatic compound.
- 3. A copolymer according to claim 1 wherein the diene is butadiene, the alkenylaromatic compound is styrene and the ethylenically unsaturated nitrile is acrylonitrile.
- 4. A core-shell copolymer comprising particles wherein the core comprises diene particles and the shell is a copolymer of an ethylenically unsaturated nitrile, an alkenylaromatic compound and vinylbenzyl azide, said shell completely surrounding and being chemically linked to said core particles.
- 5. A copolymer according to claim 4 wherein the core also comprises a copolymer of an ethylenically unsaturated nitrile and an alkenylaromatic compound.
- 6. A copolymer according to claim 5 wherein the diene is butadiene, the alkenylaromatic compound is styrene and the ethylenically unsaturated nitrile is acrylonitrile.
