SOME ASPECTS OF THE POLYMERIZATION OF NORMAL-BUTYL VINYL ETHER BY CHROMYL CHLORIDE

Results of an experimental study are presented which show that the rate of n-butyl vinyl ether polymerization by chromyl chloride is first order in left bracket catalyst right bracket and second ordin left bracket monomer right bracket . Added H//2O (after a certain concentration) and HCl increase the rate, thiophene retards the rate, while pyridine inhibits the rate. DP is independent of left bracket chromyl chloride right bracket and increases with increasing left bracket monomer right bracket up to 1M, thereafter becoming independent of it. Both rate and DP increase over the range 10-32 degree C and decrease at higher temperatures.
