Abstract

Abstract 2-(R3-C(-X)=),4,4-DI(R2-)-2-OXAZOLINE WHEREIN R2 REPRESENTS A HYDROXYMETHYL OR ALKYL RADICAL WITH 3 CARBON ATOMS, WITH AT LEAST ONE R2 HAVING TO BE A HYDROXYMETHYL RADICAL, R1 IS A HYDROCARBON WITH SINGLE OR MULTIPLE UNSATURATION AND WITH 3 TO 18 CARBON ATOMS, PREFERABLY 16 TO 18 CARBON ATOMS, AND X DENOTES H2OR=CH2,AND (C) THE ETHERIFICATION PRODUCTS ARE REACTED WITH SUCH QUANTITIES OF A,B-ETHYLENICALLY UNSATURATED MONOCARBOXYLIC ACIDS AND/OR POLYCARBOXYLIC ACIDS ACIDS AND, WHERE THEY EXIST, THEIR ANHYDRIDES AND/OR THEIR HALF-ESTERS WITH MONOALCOHOLS WITH 1 TO 4 CARBON ATOMS, OPTIONALLY IN THE PRESENCE OF OTHER VINYL OR FINYLIDENE COMPOUNDS, BY HEATING, SO THAT THE REACTION PRODUCTS HAVE AN ACID NUMBER OF AT LEAST 25, AND (D) THEREAFTER THE REACTION PRODUCTS, CONTAINING CARBOXYL GROUPS, ARE TREATED WITH SUCH AMOUNTS OF AMMONIA AND/OR STRONG ORGANIC NITROGEN BASES, UP TO COMPLETE OR PARTIAL NEUTRALIZATION, THAT THE REACTION PRODUCTS ARE ADEQUATELY CAPABLE OF DISPERSION IN WATER OR DILUTION WITH WATER. THE PRESENT INVENTION CONCERNS A PROCESS FOR THE MANUFACTURE OF VINYL-MODIFIED SYNTHETIC RESINS, WHICH CAN BE DILUTED WITH WATER, BASED ON POLYETHERS, CHARACTERIZED IN THAT IF N IS ZERO AND N" IS 2, OR IF N AS WELL AS N" IS 1, WITH N1 IN ALL CASES BEING ZERO OR A SMALL NUMBER AND WITH R1 REPRESENTING AN ALIPHATIC OR AROMATIC RADICAL, ARE ETHERIFIED BY HEATING, OPTIONALLY IN THE PRESENCE OF CATALYSTS, WITH (B)(B'') ALKANOLAMIDES OF UNSATURATED FATTY ACIDS AND/OR (B") OXALOLINES OF UNSATURATED FATTY ACIDS, OF GENERAL FORMULA: (R1-O-CH2-CH(-OH)-CH2)N1-O-R1 WHEREIN (1) Z DEMOTES AN ALKYL, ARYL OR CCYCLOALKYL RADICAL, IF EITHER N IS ZERO AND N" IS 1, N'' CAN BE 0, 1, 2 AND 3 OR (II) Z DEMOTES AN ALKYLENE, ARYLENE OF CYCLOALKYLENE RADICAL IF N AND N" IS 1 OR IF N IS ZERO AND N" IS 2, N'' CAN BE 0, 1, 2 AND 3 OR (III) Z DENOTES THE RADICAL OF THE FOLLOWING FORMULA: (OXIRANYL-CH2-O)N"-Z-(O-CH2-CH(-OH)-CH2-O-R((-OH)N''))N (A) COMPOUNDS CARRING EPOXIDE GROUPS AND OPTIONALLY ALSO HYDROXYL GROUP, OF GENERAL FORMULA
