Abstract

A caprolactone-modified acrylic polymer comprising the product obtained by polymerizing a mixture of vinyl monomers, including at least one such monomer containing a --COOH and/or --OH group, with caprolactone.

Claims

1. A process for preparing a composition comprising (a) a caprolactone-modified vinyl polymer and (b) a melamine-formaldehyde, said process comprising polymerizing caprolactone with a mixture of vinyl monomers including (1) from 60-98% by weight of a monomer selected from the group consisting of styrene, α

-substituted lower alkyl styrenes, lower alkyl esters of acrylic and methacrylic acids, acrylonitrile, methacrylonitrile, acrylamide and mixtures thereof and (2) from 40-2% by weight of at least one monomer containing a --COOH and/or --OH group, the monomer containing said --COOH or --OH group being selected from the group consisting of hydroxy alkyl acrylates and methacrylates, acrylic acid, methacrylic acid, fumaric acid, crotonic acid, itaconic acid and maleic acid and the amount of caprolactone being in the range of 0.25-15 moles per --OH and --COOH equivalent in the monomer mixture and thereafter adding said melamine-formaldehyde to the resulting polymer.
