1443073 Polymers INTEROX CHEMICALS Ltd 23 Dec 1974 [11 Jan 1974] 01352/74 Headings C3P and C3R Polymers are formed by co-reacting (1) an ethylenically unsaturated monomer containing a hydroxyl group and (2) a lactone in the presence of stannous octoate as catalyst and optionally a free radical initiator, and/or a further unsaturated monomer. An example refers to co-reacting 2-hydroxyethyl acrylate, styrene and epsilon-caprolactone in the presence of stannous octoate and azo - bis - 2 - methyl propionitrile in solution in xylene. |
