Preparation of Polymers Containing Oxadiazolone Structure

Abstract

Some polymers containing oxadiazelone ring in the side chain were synthesized by(1)polymerization of 2-phenyl-4-methacryloyl-1, 3, 4-oxadiazolin-5-one obtained by the reaction of 2phenyl-1, 3, 4-oxadiazolin-5-one with. methacrylic anhydride, methacrylic chloride or methacrylic acid, (2) polymer reaction of poly(methacrylic acid) with 2-phenyl-1, 3, 4-oxadiazolin-5-one, (3) polymerization of 2-phenyl-4-(1-azilidinylmethyl)-1, 3, 4-oxadiazolin-5-one prepared by the reaction of 2-phenyl-4-hydroxylmethyl-1, 3, 4-oxadiazolin-5-one and ethylenimine, and (4)polymer reaction of 2-phenyl-4-hydroxymethyl-1, 3, 4-oxadiazolin-5-one with pely(ethylenimine). Some properties of polymers containing oxadiazolone moiety were examined.
Further, amino acid containing oxadiazolone group, α-amino-γ (1, 4-oxadiazolin-5-on-2-yl)butyric acid was prepared from L-trglutamic acid.
