Coating composition of a mixture of a vinyl ester of an aliphatic acid-carboxylic acid copolymer and a terpolymer of a vinyl ester of an aliphatic acid,a carboxylic acid ester and a carboxylic acid

Abstract

Abstract A FIRST INTERPOLYMER OF 0.5 TO 10 MOL PERCENT OF AN ETHYLENICALLY UNSATURATED MONO- POLY-CARBOXYLIC ACID AND 99.5 TO 90 MOL PERCENT OF A VINYLIDENE ESTER OF A SATURATED ALIPHATIC ACID IS BLENDED WITH A SECOND INTERPOLYMER WHICH ACTS AS A POLYMERIC PLASTICIZER. PREFERABLY, THE FIRST INTERPOLYMER IS A COPOLYMER OF VINYL ACETATE AND CROTONIC ACID. THE SECOND INTERPOLYMER IS COMPRISIED OF 75 TO 95 MOL PERCENT OF A VINYLIDENE ESTER OF A SATURATED ALIPHATIC ACID (PRINCIPALLY VINYL ACETATE), 5 TO 25 MOL PERCENT OF AN ETHYLENICALLY UNSATURATED MONO- OR POLYCARBOXYLIC ACID HAVING AT LEAST 75% OF ITS CARBOXYLIC ACID GROUPS ESTERIFIED WITH AN ALIPHATIC ALCOHOL (PRINCIPALLY DIBUTYL MALEATE), 0.5 TO 10 MOL PERCENT OF AN ETHYLENICALLY UNSATURATED MONO- OR POLY-CARBOXYLIC ACID (PRINCIPALLY ACRYLIC ACID), AND, OPTIONALLY, ZERO TO 3 MOL PERCENT OF A GLYCIDYL ESTER OF AN ETHYLENICALLY UNSATURATED MONOOR POLY-CARBOXYLIC ACID (PRINCIPALLY GLYCIDYL METHACRYLLATE). THE INTERPOLYMER BLEND IS USEFUL FOR THE PROTECTION OF MATERIALS HAVING AT LEAST ONE FINISHED SURFACE. WHEN NO LONGER NEEDED, IT MAY BE REMOVED FROM THE SUBSTRATE BY WASHING WITH AN AQUEOUS ALKALINE SOLUTION.
