Homopolymerization of hydronopyl vinyl ether and 2‐hydronopoxyethyl vinyl ether

Abstract The effectiveness of several free radical, cationic, and coordination initiators for the polymerization of hydronopyl vinyl ether and 2‐hydronopoxyethyl vinyl ether has been examined. The most effective initiator found for polymerization of hydronopyl vinyl ether is a coordination catalyst prepared from triisobutylaluminum and titanium tetrachloride. Generally, cationic initiators are less effective and free radical initiators much less effective with this monomer. Of the initiators investigated for polymerization of 2‐hydronopoxyethyl vinyl ether, only one, boron fluoride etherate, proved to be effective. This initiator yielded a rubbery polymer of high molecular weight.
