摘要：A polyvinyl alcohol copolymer latex composition comprises an intimate polymercomposition obtained from 10% to 60% by weight of a substantially hydrolyzed lowmolecular weight polyvinyl alcohol (PVOH); 2% to 80% by weight of at least one diene;2% to 80% by weight of at least one hydrophobic monomer other than a diene andoptionally either up to 10% by weight of at least one hydrophilic ethylenicallyunsaturated acid monomer or up to 40% by weight of a cationic monomer. The

copolymer latex composition can be prepared as an emulsion from an aqueous blend ofthe above listed monomers which are generally added at various stages during thepolymerization and a free radical initiator, surfactants, and, if desirable, chain transferagents. Up to 80% of the PVOH may be added after the monomers have beenpolymerized.
