Abstract
The radical polymerization of three oligoethylene glycol methyl vinyl ethers, ethylene glycol methyl vinyl ether, diethylene glycol methyl v inyl ether, and triethylene glycol methyl vinyl ether, was examined in aqueous and in alcoholic media. These monomers showed a relatively hi gh polymerizability in aqueous media when 2,2'-azobis(2-amidinopropane ) dihydrochloride was chosen as the initiator and produced polymers of 2000<(M) over bar(n)<6600 in moderate yields. Formamide was also a go od solvent for their radical polymerization, in which polymers of (M) over bar(n)<1100 were produced. These solvents are considered to form strong hydrogen-bonds with these monomers, thus stabilizing the propag ating radical ends.
