A composition comprising a polymer according to Structure 1 wherein R is H, Me, Et or CH; R' is H or Me; n is a number from 1 to 100; and Z is a number from 1 to 3; f is a number from 1 to 5, with f=1 if B is nothing; A is residue of a hydrogenated polybutadiene backbone; and B nothing or it is a difunctional organic linking group is disclosed. The composition can be cured and used in a wide range of articles such as a photopolymer printing plate, sealant, caulk, encapsulent, road marking paint, photoresist, binder, impact modifier, polymer modifier, oxygen or water vapor barrier coating, conformal coating, solder mask, pigment dispersion, stereolithograph, laminating resin, grafted co-polymer, composite, optical fiber coating, paper coating, metal coating, glass coating, plastic coating, wood coating, waterproofing material, electrical insulating material, automotive belt or hose, tire, engine mount, gasket, golf ball core, and rubber roll.

Poly(ethylene-butylene) (meth)acrylates and related compositions

The present invention is for a new class of allyl urethane resin which can be cured with peroxide at high temperature alone or in combination with some accelerators. These allyl urethane resins can be sued alone or in combination with other free radically polymerizable materials such as allyl monomers and ligomers or (meth)acrylate monomers and oligomers. These new allyl urethane resins contain at least two allyl functional groups.

Allyl urethane resin compositions

The invention provides dental cement compositions and methods of using them for binding hard tooth material, metal and ceramic. The cement compositions include shelf stable complexes of ethylenically unsaturated monomers reacted with cations. The cements have superior adhesion to tooth without separately acid etching dentin or enamel. Compositions of are useful as dental luting cements, liners, pit and fissure seal bases and restoratives.

Dental composition and method

Polyester based polycarbonate (meth)acrylates prepared by the reaction of a alkylene or arylene diol polycarbonate with an anhydride or its dicarboxylic acid to form a carboxyl terminated diester, reacting the diester with a diglycidyl ether and an acrylic or methacrylic acid to form an acrylate terminate polymer which is useful for radiation cured coatings which have superior adhesion and reverse impact strength when applied to plastic substrates.

A preferred embodiment of the invention provides a composition and method of treating dental metal. The composition includes a polymerizable aryl compound having at least one carboxylic acid group and at least one polymerizable group, and a polymerizable compound having at least one polymerizable group and at least one phosphorous containing group. A preferred composition includes at least 50 percent by weight of a volatile organic solvent, at least 15 percent by weight of one or more polymerizable acrylate compounds and an effective amount of a photoinitiator. At least a portion of the polymerizable compounds are multifunctional polymerizable compounds having at least three acrylate moieties. The polymerizable compounds are substantially soluble in the solvent. The composition is adapted to form a polymeric material which is adapted to adhere to metal and ceramics and to dentin. Compositions of the invention have superior adhesion to dental metals and tooth without separately acid etching dentin or enamel. Compositions are useful as dental priming adhesives, luting cements, liners, pit and fissure sealants, bases and restoratives.
