POLYMER COMPOUND HAVING STAINPROOF ACTIVITY AND STAINPROOFING MATERIAL CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polymer compound combining a gramine analogue and useful as a stainproofing material. ;SOLUTION: There is provide a gramine analogue-combined polymer compound of formula I. The compound is obtained by converting a compound of formula II in the case where R represents a member other than hydrogen into a free carboxylic acid by hydrolysis with an acid or alkali, and condensing with a monomer for a polymer having a polymerizable functional group and a substituent reactive with the carboxylic acid for conversion into an ester or amide compound of the monomer. The resultant compound of formula III is mixed with a co-monomer in an amount of 1 to 50% and polymerized to obtain the polymer compound. Alternatively, the polymer compound is obtained by subjecting the compound of formula II (wherein R is H) to condensation or substitution with a polymer having a functional group. In the formulas, A represents H or a halogen; B represents H or diemthylaminomethyl; (m) and (n) are each an integer including zero; X represents oxygen, sulfur or amino; and Y represents a polymer compound and E represents a group polymerizable to a polymer having styryl, vinyl, allyl or the like.;COPYRIGHT: (C)2000,JPO
