Abstract: THE PRESENT INVENTION RELATES TO A PROCESS FOR PRODUCING A LACQUER RESIN COMPONENT FOR BAKING VARNISHED WHEREIN ESTERIFIED-ALKOXYLATED COPOLYMERS ARE PRODUCED IN A SEQUENTIAL THREE STAGE PROCESS COMPRISING COPOLYMERIZING VINYL AROMATIC HYDROCARBON AND MALEIC ACID ANHYDRIDE AND EQUENTIALLY HALF ESTERIFYING AND ALKOXYYLATING THE RESULTANT COPOLYMER. ALL THREE STAGES OF THE PROCESS ARE CONDUCTED IN A CONTINUOUS PHASE IN THE PRESENCE OF A DISPERING AGENT AND A HIGH BOILING LIQUID HYDROCARBON SOLVENT MEDIUM, SAID HYDROCARBON BEING PREFERABLY OF A SUBSTANTIALLY NON-AROMATIC NATURE, SAID DISPERSING AGENT BEING A COPOLYMER OF (1) ESTERS FORMED FROM ALPHA, BETA-UNSATURATED CARBOXYLIC ACIDS AND LONG CHAIN ALIPHATIC ALCOHOLS IN THE ANGE OF FROM C10 TO C20 CADBONS OR MIXTURES THEREOF AND (2) ETHYLENICALLY UNSATURATED COPOLYMERIZABLE COMPOUNDS.

Abstract: RESIN PRODUCTS ARE PREPARED BY ALKOXYLATION OF COPOLYMERS OF VINYL AROMATIC HYDROCARBONS SUCH AS STYRENE, WITH ALPHA, BETA-UNSATURATED DISCARBOXYLIC ACID HALF ESTERS SUCH AS THE MALEIC ACID-N-BUTYL HALF ESTER. THE THUS-FORMED RESIN PRODUCTS ARE USEFUL AS LACQUER RESIN COMPONENTS FOR BAKING VARNISHES.
