Solutions of polymers in oxazolines and polymerizates thereof

Claim 1

A solution comprising a polymer which is not reactive with oxazolines selected from the group consisting of polyesters, polyethers, polysulfones, polyamides, polycarbonates, polyphenylene oxides, styrene-acrylonitrile copolymers, polyoxazolines, polyacrylates, and polyurethanes in a liquid oxazoline having formula I or formula II or both ##STR2## wherein R and R'" independently represent hydrogen, an alkyl group having from 1 to 10 carbon atoms or a hydroxy alkyl group having from 1 to 10 carbon atoms, R' represents hydrogen, an alkyl group having from 1 to 19 carbon atoms, an aryl group having from 6 to 12 carbon atoms, or a hydroxy alkyl group having from 1 to 19 carbon atoms, and R" represents an alkylene group having from 1 to 12 carbon atoms or an arylene group having from 6 to 12 carbon atoms in which said polymer is present in from about 10 to 50% by weight of the solution and which solution also contains an additive selected from the group consisting of polyisocyanates, polycarboxylic acids, carboxylic acid anhydrides, polyphenolic compounds containing two or more phenolic hydroxyl groups, thiols, acrylic acids and polyepoxides.
