Abstract (en)

[origin: WO9509876A1] A copolymer preparable by the emulsion polymerisation of: a) at least one monomer which comprises an alkyl methacrylate having from 1 to 12 carbon atoms in the alkyl group; a vinyl aromatic; or a nitrile having ethylene unsaturation conjugated with the nitrile group, with at least one of the following: b) at least one copolymerisable soft monomer; and c) at least one copolymerisable functional monomer, the resulting copolymer having a glass transition temperature (Tg) from -35 DEG C to 50 DEG C and being formulatable into a coating which is cold sealable to itself under pressure but which has non-blocking characteristics.
