PROCEDURE FOR THE PREPARATION OF A SYNTHETIC RESIN BASED ON AN ACRYLATE POLYMER CONTAINING EPOXY GROUPS. THEY ARE COPOLYMERIZED FROM 20 TO 90% IN WEIGHT OF ALKYL ESTER OF ACRYLIC ACID WITH 1 TO 18 ATOMS OF CARBON IN THE RADICAL ALKYL AND / OR ESTER OF METACRILIC ACID WITH 1 TO 20 ATOMS OF CARBON IN THE RADICAL ALKYL, FROM 5 TO 40% BY WEIGHT OF A HYDROXYALKYL ESTER OF ACRYLIC ACID AND / OR METACRILIC ACID AND FROM 5 TO 40% BY WEIGHT OF ACRYLIC ACID AND / OR OTHER METHYRIDALLY INSURATED, OXYPHINICALLY INSURATED, OXYPHINICALLY INSURATED, AXYCHINIC ACID, AND ANOTHER THE HYDROXYL GROUPS OF ACRYLATE COPOLYMER, BEFORE OR AFTER COPOLYMERIZATION, AT LEAST PARTIALLY, WITH A PARTIALLY BLOCKED DIISOCYANATE AND / OR POLYISOCYANATE. IT IS USED AS A BINDER IN VARNISHES FOR OVEN DRYING AND IN POWDERED VARNISHES. |
