Copolymers of monounsaturated or diunsaturated polyesters with vinyl monomers

Abstract

Abstract The invention provides new copolymers of (I) monounsaturated or diunsaturated addition polymerizable polyester monomers and (II) vinyl monomers. The resulting copolymer is considered to be a vinyl polymer (e.g., an acrylic polymer) containing a pendant polyester plasticizer as an integral part of the polymer. It is not essential that the copolymer be crosslinked or thermoset, and yet the plasticizer is a permanent part of the polymer--not subject to being leached out of the polymer, as is the case with an external plasticizer. While thermosetting or crosslinked compositions are known which bind external plasticizers to the substrate, the very object of attaining flexibility is to a large extent defeated by the binding agent itself when present in large amounts. Also provided are new monomers in the form of unsaturated polyesters having one or two double bonds per molecule. Textile articles characterized by improved water-resistance, wet abrasion or crock resistance, softness of hand, wet and dry peel strengths, washfastness, drycleanability and higher flock density, are obtained by following the invention. One of the important advantageous properties of the polymer of the invention is the cold flexing strength of products such as flocked fabrics made therewith. Other coated, bonded, impregnated, and laminated articles are provided.
