Abstract

Graft polymers are made by polymerizing from 95 to 5% by weight of a monomer composition (1) containing from 30 to 100% by weight of vinyl and/or vinylidene chloride and from 70 to 0% by weight of a different monoethylenically unsaturated polymerizable compound containing a -CH=C< group with from 5 to 95% by weight of a polymer in solution and formed by polymerization of a monomer composition (2) containing from 1 to 100% of a monomer represented by the formulae <FORM:0824920/IV (a)/1> (methacrylamides) <FORM:0824920/IV (a)/2> and <FORM:0824920/IV (a)/3> (itaconamates) and <FORM:0824920/IV (a)/4> (substituted acrylates) wherein R and R1 represent H or a C1-C6 alkyl group, R2 represents a methyl, ethyl, acetamino or carbethoxyamino group and R3 represents a C1-C4 alkyl group, and from 99 to 0% of a different monoethylenically unsaturated compound containing a -CH=C< group, the percentages of monomer being based on the total weight of compositions (1) and (2). The preformed polymer may be dissolved in water, in aqueous acetone or organic solvents such as acetonitrile, benzene, toluene, heptane, aliphatic ethers or acetone. Polymerization may be accelerated by heat, light and catalysts such as peroxy compounds (listed), azines and ketazines. Also present during polymerization may be specified emulsifiers, mercaptans and alkali metal bisulphites. Polymerization may be carried out batchwise or continuously and, if desired, in two stages whereby further chloride monomer is polymerized in the presence of a graft polymer formed previously. The polymers are compatible with polyvinyl and polyvinylidene chlorides and may be dissolved in acetone, methyl ethyl ketone and polyacrylonitrile solvents, from which solutions films and fibres may be made. Specification 651,155 also is referred to.
