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. |
