Silylated addition polymers with pendant ionic moieties

An addition polymeric reaction product, comprising:

• a. at least one ethylenically unsaturated monomer having at least one ionic moiety per monomer and where the ionic moiety is selected from the group consisting of:
• sulfonates and quaternary ammonium salts and mixtures thereof in an amount to produce the polymerized reaction product in the polymer in an amount of up to 99 weight percent of the polymer;
• and
• b. a copolymerizable organofunctional silane compound selected from the group consisting of acrylatoorganoalkoxysilanes, methacrylatoorganoalkoxysilane, and vinylorganoalkoxysilanes where the alkoxy group has alkyl groups with up to five carbon atoms or partial or fully hydrolyzed derivatives in an amount in the range of about 1 to about 15 weight percent of the polymer;
• and where the addition polymeric product is formed in the presence of a water miscible free-radical initiation catalyst in an effective catalytic amount and in the presence of water in at least an effective dispersing amount and at an elevated temperature in the range of about 80.degree. C. to about 90.degree. C. for a period of time at least to approach complete polymerization, wherein the addition polymer has pendant ionic moieties and pendant silane moieties that have groups selected from the group consisting of hydrolyzable, hydrolyzed and partially hydrolyzed groups.
