Abstract
PURPOSE: To obtain the title product by saponification, in an alkaline medium, of a copolymer from ethylene, a vinyl ester, and an ethylenic unsaturated carboxylic acid (or its derivative), in the presence of hydrazine.
CONSTITUTION: The objective product can be obtained by saponification, in an alkaline medium, of a copolymer from ethylene, a vinyl ester, and an ethylenic unsaturated carboxylic acid (or its derivative), in the presence of hydrozine or its derivative. The preferable composition of said copolymer is as follows: (1) a molar ratio vinyl ester (X): ethylenic unsaturated carboxylic acid or its devirative (Y)= 20:80W80:20, (2) Z: (X+Y)=0:100W15:85 here, Z is mole number of the ethylene component. Said vinyl ester is, e.g., vinyl acetate, vinyl stearate. As the ethylenic unsaturated carboxylic acids or their derivatives, are mentioned acrylic acid, malic anhydride, and esters therefrom.
