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.

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: A MOLDING COMPOSITION WHICH MAY BE CURED TO A POLYURETHANE-BOUND MATERIAL PREPARED BY MIXING OF BETWEEN ABOUT 80 AND 98 WT. PERCENT SAND, BETWEEN ABOUT 1 TO 10 WT. PERCENT OF A DIISOCYANATO COMPOUND AND BETWEEN ABOUT 1 AND 10 WT. PERCENT OF A POLYALKOXYLATED COPOLYMER MATERIAL SELECTED FROM THE GROUP CONSISTING OF (A) AN ALKOXYLATED COPOLYMER OF STYRENE AND A HALF ESTER OF AN UNSATURATED DICARBOXYLIC ACID, (B) A MIXTURE OF THE ALKOXYLATED COPOLYMER OF (A) AND A PHENOLFORMALDEHYDE RESIN, (C) A MIXTURE OF THE ALKOXYLATED COPOLYMER OF (A) AND AN ALKANONE-FORMALDEHYDE CONDENSATION PRODUCT, AND (D) A MIXTURE OF THE ALKOXYLATED COPOLYMER OF (A) AND AN ALKYD RESIN.
