TEMPLATE POLYMERIZATION OF MULTIACRYLATE

By reacting poly(2-hydroxyethyl methacrylate) with acryloyl chloride, multiacrylate connected through a covalent bond with polymethacrylate chain (template) has been obtained. The free-radical polymerization of multiacrylate in dilute dioxane solutions at 75 degrees C and 85 degr ees C was examined by IR spectrophotometry and the distribution of mol ecular weights of the resultant products was evaluated by gel permeati on chromatography. The findings show that under selected conditions th e polymerization proceeds along ordered acrylic double bonds on the te mplate and results in a ladder-type polymer. At a temperature of 85 de grees C, in addition to the intramolecular cyclopolymerization, interm olecular reactions proceed to a minor extent. (C) 1994 John Wiley & So ns, Inc.
