General description

2-Methyl-2-oxazoline undergoes polymerization with 2-butyl-2-oxazoline to form poly(2-oxazoline) block copolymer. It undergoes cationic ring-opening polymerization with 2-(dec-9-enyl)-2-oxazoline to yield copoly(2-oxazoline)s.

Application

2-Methyl-2-oxazoline was used in cationic polymerization of a series of linear 2-alkyl-2-oxazolines under microwave irradiation.
