摘要:
A method of sizing paper, comprising applying thereto a sizingly effective amount of a polymer selected from the group consisting of:(a) homopolymers of .alpha.,.alpha.-dimethyl-m-isopropenyl benzyl amine or .alpha.,.alpha.-dimethyl-p-isopropenyl benzyl amine;(b) copolymers of (i) .alpha.,.alpha.-dimethyl-m-isopropenyl benzyl amine or .alpha.,.alpha.-dimethyl-p-isopropenyl benzylamine, and (ii) at least one other ethylenically unsaturated monomer copolymerizable therewith; and(c) acid salts of said homopolymers (a) and copolymers (b).Such homopolymers or copolymers suitably may be prepared as the hydrolysis reaction products of the corresponding homopolymeric or copolymeric isocyanates.
