Method for manufacturing waterdilutable,vinyl modified synthetic resins based on polyether esters

Abstract

Abstract PREFERRED ARE THE POLYETHERESTERS OF THIS INVENTION, USABLE FOR THE MANUFACTURE OF ELECTROPHORETICALLY DEPOSITABLE SYNTHETIC BINDERS, WHICH ARE OBTAINED WHEN THE NEW POLYETHERESTERS ARE MIXED TOGETHER WITH PHENOPLASTS AND/OR AMINOPLASTS BEFORE THE NEYTRALIZATION WITH AMMONIA OR AMINES AND ARE SUBJECTED TO A PRECONDENSATION BY HEATING TO TEMPERATURES OF 100* TO 150*C., THE HEATING OF THE MIXTURE BEING INTERRUPTED IMMEDIATELY IF THE FORMED PRECONDENSATE HAS REACHED THE NECESSARY ACID NUMBER. (E) MIXED WITH SUCH AMOUNTS OF AMMONIA AND/OR STRONG ORGANIC NITROGEN BASES UP TO COMPLETE OR PARTIAL NEUTRALIZATION, UNTIL THE REACTION PRODUCTS ARE SUFFICIENTLY DISPERSIBLE OR WATER-DILUTABLE. AND (D) REACTED WITH SUCH AMOUNTS OF A,B-ETHYLENICALLY UNSATURATED MONO OR POLYCARBOXYLIC ACIDS POSSIBLY IN THE PRESENCE OF OTHER VINYL OR VINYLIDENE COMPOUNDS, BY HEATING, SO THAT THE REACTION PRODUCTS HAVE AN ACID NUMBER OF AT LEAST 25, THEREAFTER (C) THE ETHERIFICATION PRODUCTS WITH ALIPHATIC MONOCARBOXYLIC ACIDS WITH 6-20 C ATOMS, CONTAINING PREFERABLY ONE OR MORE ETHYLENIC DOUBLE BONDS, THEN ESTERIFIED WITH (B) MONOVALENT ALCOHOLS WITH 3-20 C ATOMS, HAVING AT LEAST ONE AND PREFERABLY SEVERAL ETHYLENIC DOUBLE BONDS, BY HEATING, ETHERIFIED WITH WATER-DILUTABLE, VINYL MODIFIED SYTHETIC RESINS BASED ON POLYTHERESTERS WHICH ARE REACTION PRODUCTS OF (A) COMPOUNDS CARRYING EPOXY GROUPS AND POSSIBLY ALSO HYDROXYL GROUPS,
