Statistical group transfer copolymerization. Monomer reactivity ratios for allyl methacrylate and n-butyl methacrylate

Abstract

Abstract Statistical copolymerizations have been performed for allyl methacrylate-butyl methacrylate systems using 1-methoxy-2-methyl-1-trimethylsilyloxypropene (initiator) and tris (dimethylamino) sulphonium bifluoride (catalyst) in tetrahydrofuran solution. Soluble allyl copolymers have been obtained by this method. The copolymer compositions were determined by ultraviolet spectroscopy and the results evaluated by the Kelen-Tudos and Fineman-Ross methods. The reactivity ratios were found to be r AMA = 2.35, r BMA = 0.08 (Kelen-Tudos) and r AMA = 2.37, r BMA = 0.08 (Fineman-Ross).
