obtaining a co-catalytically effective quantity of a triethoxonium salt which is
capable of acting as a co-catalyst of a polymerization reaction of said cyclic ether
monomer;
obtaining a co-catalytically effective quantity of an alcohol which is capable of
acting as a co-catalyst of a polymerization reaction of said cyclic ether monomer;
combining said salt and said alcohol to form a polymerization catalyst mixture;
adding said cyclic ether to the mixture of said salt and said alcohol in a non-
polar solvent and allowing polymerization of said cyclic ether to occur and allowing said
salt to scavenge trace water contained within said mixture such that a polymer of
controlled functionality is
rapidly produced.
