COPOLYMERIZATION OF 2-VINYLOXYETHYL ISOTH IOCYANATE WITH ACRYLIC-ACID

Depending on the reaction conditions, radical copolymerization of 2-vi nyloxyethyl isothiocyanate with acrylic acid yields linear alternating oligomers, partially cross-linked and strongly swelling copolymers, a nd densely cross-linked polymeric products of porous network structure . It was shown that, in strongly swelling polymeric products, the cros s-links are formed not only by the cross-linking agent but also by the units formed by the reaction of isothiocyanate and carboxyl groups of the comonomers. Sol-gel analysis of the polymerizing system was perfo rmed, and some kinetic data describing the copolymerization were obtai ned.
