Abstract

Abstract WHEREIN X is an alkyl, acrylic or cycloalkyl group, Y is an alkylene, arylene or cycloalkylene group, N'' IS 0 OR A SMALL INTEGER, N1 IS 0 OR A SMALL INTEGER, R1 is an aliphatic or aromatic group, and R is an aliphatic or aromatic group. B. THE UNSATURATED MONOHYDRIC ALCOHOL HAS THREE TO 20 CARBON ATOMS AND THE ETHERIFICATION IS CARRIED OUT BY HEATING, C. THE CARBOXYLIC COMPOUND IS AN Alpha , Beta -ETHYLENICALLY UNSATURATED MONOCARBOXYLIC OR POLYCARBOXYLIC ACID, AN ANHYDRIDE AND/OR A HALF ESTER WITH MONOALCOHOLS HAVING ONE TO FOUR CARBON ATOMS, OPTIONALLY CONTAINING VINYL OR VINYLIDENE COMPOUNDS, AND THE COPOLYMERIZATION REACTION IS CARRIED OUT WITH HEATING SO THAT THE REACTION PRODUCTS HAVE AN ACID NUMBER OF AT LEAST 25, AND D. THE NEUTRALIZATION IS CARRIED OUT IN THE PRESENCE OF AMMONIA, STRONG ORGANIC NITROGEN BASES OR MIXTURES THEREOF SO THAT THE REACTION PRODUCTS ARE DISPERSIBLE IN OR DILUTABLE WITH WATER. Water-dilutable vinyl modified polyether resins produced by etherifying an epoxide compound with an unsaturated monohydric alcohol containing at least one ethylenic double bond, copolymerizing the etherified product through its centers of unsaturation with an ehtylenically unsaturated carboxylic compound and neutralizing the copolymer wherein: A. THE EPOXIDE COMPOUND IS SELECTED FROM THE GROUP CONSISTING OF
