Abstract:
Described herein are compositions containing a reactive monomer derived from the reaction product of a hydroxyalkyl acrylate or methacrylate and a lactone. These compositions can be reacted with other ethlenically unsaturated monomers to produce curable oligomers and polymers than can be made into high quality industrial finishes by incorporation of various conventional crosslinking agents, plus other normally used formulating ingredients.
Abstract:
This invention is directed to adducts of a polycaprolactone polyol and a polyepoxide comprising the reaction product of at least one polycaprolactone polyol and a polyepoxide containing two or more epoxy groups per molecule in a molar ratio of polycaprolactone polyol to polyepoxide of from about 2:1 to about 3:1, said adducts having an oxirane content of less than about 0.10 percent and a viscosity of less than about 3700 centistokes at 54.5.degree. C. The adducts are useful in the formulation of high solids coating compositions, polyurethane elastomers, inks, sealants, adhesives and the like.
Abstract:
Described herein are compositions suitable for photocopolymerization comprising (a) an epoxide containing two or more epoxy groups, and (b) a hydroxyl substituted cycloaliphatic monoepoxide. The composition may additionally contain a poly (active hydrogen) organic compound and/or a photoinitiator. A coating produced from such a composition has a good combination of properties. Especially preferred are compositions further containing a vinyl cycloaliphatic monoepoxide and diazonium or onium photoinitiator.
Abstract:
Described herein are stabilizers for curable compositions containing cycloaliphatic epoxides and a catalyst. A molded article produced from such a composition possesses high mechanical properties.
Abstract:
High solids coating compositions comprising a polycaprolactone derivative and a mixture of a methylolated melamine and a low molecular weight polyol; and, optionally, solvent and catalyst. The polycaprolactone derivative used in the coating compositions is the reaction products of a polycaprolactone polyol, a diepoxide and an anhydride of a polycarboxylic acid; the polycaprolactone polyol has an average of at least two hydroxyl groups in the molecule, a hydroxyl number of from about 15 to about 600 and an average molecular weight of from about 290 to about 6,000. The carboxylic acid anhydride mentioned has at least one intramolecular carboxylic anhydride group. The polycaprolactone derivatives are water insoluble.
Abstract:
Mixtures of the unsaturated maleic anhydride modified adduct of a polycaprolactone polyol and an ethylenically unsaturated monomer are copolymerized. The resulting polymers are useful as coatings or in the production of films and shaped molded articles.
