Anwendungen & Verwendung
Verwenden
2-Methyl-2-oxazoline is used in cationic polymerization of a series of linear 2-alkyl-2-oxazolines under microwave irradiation. It 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. It react with N'-phenyl-benzohydrazonoyl chloride to get 4-(2-hydroxyethyl)-5-methyl-1,3-diphenyl-1,2,4-triazol-4-ium chloride.
