Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
113 words
A composition suitable for films, coatings, binders and adhesives consisting essentially of: A. an emulsion of a copolymer of an ethylenically unsaturated carboxylic acid and one or more comonomers, said ethylenically unsaturated acid being about 0.1 to 20% by weight of said copolymer and B. an aqueous solution of a polymer of at least 10% by weight of one or more monomers of the formula: ##STR3## or mixtures thereof wherein R is an ethylenically unsaturated group; R 1 is a linear C 1 to C 4 alkyl or hydroxyalkyl group; X is chlorine, bromine, or iodine; and Y - is an anion; the ratio of B to A being about 1/1000 to 1/1.
Claim 2
Dependent Claim
113 words
A composition suitable for films, coatings, binders and adhesives consisting essentially of: A. an emulsion of a copolymer of an ethylenically unsaturated carboxylic acid and one or more comonomers, said ethylenically unsaturated acid being about 0.1 to 20% by weight of said copolymer and B. an aqueous solution of a polymer of at least 10% by weight of one or more monomers of the formula: ##STR3## or mixtures thereof wherein R is an ethylenically unsaturated group; R 1 is a linear C 1 to C 4 alkyl or hydroxyalkyl group; X is chlorine, bromine, or iodine; and Y - is an anion; the ratio of B to A being about 1/1000 to 1/1.
