Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
108 words
A polymer of (a) 1 to 100 weight percent of an ethylenically unsaturated 1,3,2,4-dioxathiazole-2-oxide compound of the formula ##STR7## in which R 1 is H or methyl, R 2 is H, COOR, COOM, CONHR or ##STR8## wherein M is a metal cation and R is H, alkyl, cycloalkyl or aryl, and X is OCH 2 , ##STR9## in which n is from 1 to 50, and (b) 0 to 99 weight percent of a dissimilar ethylenically unsaturated monomer, said dissimilar monomer being devoid of groups which are reactive with cyclic dioxathiazole-2-oxide of said polymer under polymerization conditions, said polymer having a molecular weight of from 1,000 to 3,000,000.
Claim 2
Dependent Claim
108 words
A polymer of (a) 1 to 100 weight percent of an ethylenically unsaturated 1,3,2,4-dioxathiazole-2-oxide compound of the formula ##STR7## in which R 1 is H or methyl, R 2 is H, COOR, COOM, CONHR or ##STR8## wherein M is a metal cation and R is H, alkyl, cycloalkyl or aryl, and X is OCH 2 , ##STR9## in which n is from 1 to 50, and (b) 0 to 99 weight percent of a dissimilar ethylenically unsaturated monomer, said dissimilar monomer being devoid of groups which are reactive with cyclic dioxathiazole-2-oxide of said polymer under polymerization conditions, said polymer having a molecular weight of from 1,000 to 3,000,000.
