Abstract: A method of acylating starch with dibasic acid anhydrides and forming salts of the acylated starch with amines devoid of Zerewitinoff hydrogen at pH 5.0-7.0 The resultant amine slats of the starch half esters are useful as sizing agents for yarns containing synthetic fibers.

Abstract: HYDROPHILIC AMIDE POLYMERS ARE OBTAINED BY INTERPOLYMERIZING MONOMERS OF AN ETHYLENICALLY UNSATURATED MONOCARBOXYLIC ACID, ETHYLENICALLY UNSATURATED HARD MONOMERS OF THE LOWER ALKYL ESTERS OF AN ACRYLIC ACID AND A SOFT ALKYL ESTER OF AN ALPHA, BETA-ETHYLENICALLY UNSATURATED CARBOXYLIC ACID AND ACYLATING WITH HYDROPHILIC AMINES. THE POLYMERIZED MONOMERIC UNITS ARE SUFICIENT TO PROVIDE AN AVERAGE POLYMER TG RANGING FROM ABOUT 35* TO ABOUT 45*C. AND A WEIGHT AVERAGE MOLECULAR SIZE (AW) OF ABOUT 500 TO 5,O00.
