Preparation of ring-opening polymerizable macromer and its copolymerization leading to graft copolymer

Polymer Bulletin Aims and scope Submit manuscript

Summary

A poly (ethylene oxide) macromer (1) having a ring-opening polymerizable 2-oxazoline group at the end has been prepared starting with 2-(p-hydroxyphenyl)-2-oxazoline (4). Cationic ring-opening homo-polymerization of 1 took place to give a comb-like polymer having poly(ethylene oxide) branches. Cationic copolymerization of 1 with 2-phenyl-2-oxazoline(2) produced graft copolymer of poly [(2-phenyl-2-oxazoline)-g-(ethylene oxide)](3). From the results of fractional reprecipitation of 3 the polymerizability of 1 is considered to be less due at least partly to the electronic effect of p-alkoxy group in 1 than that of monomer 2.
