Abstract
A process of polymerizing a monomer mixture containing from 3 to 100% of amines containing two or more allyl groups which method comprises reacting a solution of the monomer mixture in a concentrated mineral acid in the presence of a polymerization initiator and isolating the polymer salt so formed.
Claims11
A process of polymerizing a monomer mixture containing from 3 to 100% of amines comprising at least two allyl groups which method comprises reacting a solution of the monomer mixture in concentrated phosphoric acid of concentration not less than 40% w/w and wherein the molar ratio of acid to amine is greater than 2:1, and in the presence of a polymerization inhibitor and isolating the polymer salt so formed.
