Abstract
Abstract A monomer mixture (B) containing a vinyl monomer having a functional silyl group of the general formula (ii) is subjected to emulsion polymerization in an aqueous solution of a water-soluble resin (A) having a functional silyl group of the general formula (i) the water-soluble resin [A] is synthesized using, as a polymerization solvent, a water-soluble organic solvent containing a (poly)ethylene glycol monoalkyl ether of the general formula HO-(CH2CH2O)n-R3 or a (poly)propylene glycol monoalkyl ether of the general formula HO-(C3H6O)n-R4; <IMAGE> (i) <IMAGE> (ii) wherein R1 and R2 each independently is a monovalent group selected from the class consisting of alkyl groups containing 1 to 10 carbon atoms, aryl groups and aralkyl groups, X is a group selected from the class consisting of halogen atoms, alkoxy groups, a hydroxy group, acyloxy groups, an aminoxy group, a phenoxy group, thioalkoxy groups and an amino group, a and b each independently is an integer of 0 to 2, R3 and R4 each is an alkyl group containing 1 to 10 carbon atoms and n is an integer of 1 to 10 and wherein, when two or more R1 and/or R2 or X groups are bound to Si, they respectively may be the same or different.

Claim 1
Independent Claim
276 words
An aqueous dispersion composition obtained by subjecting a monomer mixture (B) containing a vinyl monomer having a functional silyl group of the general formula ##STR5## to emulsion polymerization in an aqueous solution of a water-soluble resin (A) containing a functional silyl group of the general formula ##STR6## the water-soluble resin (A) being synthesized using a polymerization solvent, the polymerization solvent being a water-soluble solvent comprising a (poly)ethylene glycol monoalkyl ether of the general formula HO--(CH 2 CH 2 O) n --R 3 or a (poly)propylene glycol monoalkyl ether of the general formula HO--(C 3 H 6 O) n --R 4 (C 3 H 6 being a propylene group), wherein, in the above formulas, R 1 and R 2 each independently is a monovalent group selected from the class consisting of alkyl groups containing 1 to 10 carbon atoms, aryl groups and aralkyl groups, X is a group selected from the class consisting of halogen atoms, alkoxy groups, a hydroxy group, acyloxy groups, an aminoxy group, a phenoxy group, thioalkoxy groups and an amino group, a and b each independently is an integer of 0 to 2, R 3 and R 4 each is an alkyl group containing 1 to 10 carbon atoms and n is an integer of 1 to 10 and wherein, when two or more R.sup. 1 and/or R 2 or X groups are bound to Si, they respectively may be the same or different; the water-soluble resin (A) being rendered soluble in water by incorporating a monomer selected from the group consisting of a carboxyl-containing monomer and a basic group-containing monomer; the carboxyl or basic group of the water-soluble resin (A) being neutralized.
