High-Performance UV-Curable Urethane Acrylates via Deblocking Chemistry
Research in urethane-acrylate UV-curables has shown that these materials have mechanical properties inferior to those of thermoplastic polyurethanes with very similar composition owing to the high cross-link density in UV-curables; in particular, their ultimate extension is low (less than 100%). Past attempts a t increasing the ultimate extension involved compromising the advantages of the UV-c...
متن کاملAcrylates.
ACRYLATES HAVE been around since the 1930s, when Rohm and Haas began mass production of Plexiglas, a clear and resistant glass substitute made of polymerized methacrylate. It is used extensively for windowpanes, airplane canopies, car lights and windshields, streetlamps, and so on. Numerous other acrylates have been synthesized and have found applications in paints and adhesives, dental composi...
متن کاملEnvironmental Friendly Polyurethane Coatings Based On Hyperbranched Resin
Water borne polyurethane (PU) based on newly prepared hyperbranched poly (amine-ester) (HBPAE) was applied and evaluated as organic coating material. HBPAE was prepared through one-pot synthesis between trimethylol propane as a core and AB2 branched monomer which was obtained via Michal addition of methyl methacrylate (MMA) and diethanol amine (DEA). PU was prepared from HBPAE using different r...
متن کاملBackbone-thermoresponsive hyperbranched polyethers.
A new type of materials, the backbone-thermoresponsive hyperbranched polyether, was successfully synthesized by proton-transfer polymerization of 1,4-butanediol diglycidyl ether and various triols, and the lower critical solution temperature (LCST) values can be readily adjusted from 19.0 to 40.3 degrees C by changing the hydrophilic/hydrophobic balance of BDE and triols.
متن کاملUrethane therapy in leukemia.
T HE purpose of this paper is to report the results of urethane therapy of the leukemias, based on a study of 2.4 patients. In April, 1946, Haddow and Sexton’ described the influence of various carbamic esters on experimental rat cancers. Ethyl carbamate (urethane) yielded the best results. It alone produced inhibition of tumor growth and fibrous replacement of the cancerous rat tissue. For thi...
