Syntheses and Polymerization of Unsaturated Dibasic Acid Derivatives (V) Syntheses and Polymerization of Maleamic Acid Esters

摘要

Ethyl β-oxyethy1maleamateand N.N bis (β-oxyethyl)ethylmaleate were prepared bythe reaction of diethylmaleate with mono-and diethanolamine.Bis(β-oxyethyl) maleamic acid was also prepared from maleic anhydride and diethanolamine in acetone.Ethyl β-oxyethylmaleamateand N. N bis (β-oxyethyl)ethylmaleate did not homopolymerizeunder the conditions employed. but do copolymerize with styrene. Incorporationof maleamic acid ester was low in the copolymer.It is conc1uded that the N-alkyl maleamic acid esters exhibit polymerization reactionssimi1ar to other I, 2-disubstituted ethylenes.
