摘要： Poly(vinylamine salts of mineral acids are produced by reacting acetaldehyde and acetamide at a mole ratio of 1:2-4 with acid catalyst, cracking the ethylidene-bisacetamide which results into vinylacetamide, polymerizing the vinylacetamide with a free radical polymerization catalyst, and hydrolyzing the poly(vinylacetamide) to the desired amine salts by contacting the polyvinylacetamide with an aqueous solution of the corresponding mineral acid. This product may be converted to the free amine, which in turn may function as a precursor in the manufacture of certain polymeric dyes and colorants.
