Abstract
Abstract Mixtures of compounds having the formula ##EQU1## where Y is an alkyl triprimary oxy radical, Ar is a divalent radical containing an aromatic nucleus, X is aryloxy or alkoxy, B is dialkylamino or lactam-N-yl, Q is 0, 1, 2 or 3, which may be dissolved in compatible solvents and mixed with suitable catalysts and used as a coating material on organic polymers such as polyester to enhance adhesion between the substrate and a subsequently applied organic polymer such as an elastomeric polymer.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
165 words
A composition comprising a mixture of compounds having the formula ##EQU2## where Y is an alkyl triprimary oxy radical having 4 to 15 carbon atoms formed by the reaction of a triprimary alcohol selected from the class consisting of trimethylol methane, 1,1,1 trimethylol propane, 1,1,1 trimethylol dodecane, and 1,2,3 trimethylol butane and an isocyanate group, Ar is a divalent radical containing at least one aromatic nucleus, and is selected from the class consisting of phenyl, methyl phenylene, and methylene-bis-phenyl, X is a radical selected from the class consisting of aryloxy having an aliphatic side chain of 1 to 12 carbon atoms and alkoxy having 10 to 18 carbon atoms, B is lactam-N-yl, Q is 0, 1, 2, or 3, the total number of X radicals in said mixture being at least equal to the total number of B radicals in said mixture, and the total number of B radicals in said mixture is at least 10% of the sum of the B and X radicals.
Claim 2
Dependent Claim
