Photo-crosslinked Non-Isocyanate Polyurethane Acrylate (NIPUA) coatings through a transurethane polycondensation approach

A transurethane polycondensation pathway has been used to produce acrylate terminated Non-Isocyanate PolyUrethane (NIPUA) oligomers (A-Ol) with controlled molecular weights and chemical structures. These compounds were then photo-crosslinked under UV radiations to afford several NIPU acrylate coatings. The influence of the content in urethane functions as well as the chemical structures on the thermal and mechanical properties of the final coatings has been demonstrated. The obtained coatings exhibited thermal stabilities above 255 °C, Young modulus ranging from 2.6 to 9.2 MPa, tensile strength up to 11.8 MPa and elongation at break varying from 20 to 520percent.

METHOD FOR PRODUCTION OF ISOCYANATE USING COMPOSITION COMPRISING CARBAMIC ACID ESTER AND AROMATIC HYDROXY COMPOUND, AND COMPOSITION FOR TRANSPORT OR STORAGE OF CARBAMIC ACID ESTER

An object of the present invention is to provide an isocyanate production process, which is free of the various problems found in the prior art, and which uses a composition containing a carbamic acid ester and an aromatic hydroxy compound when producing isocyanate without using phosgene, as well as a carbamic acid ester composition for transferring or storing carbamic acid ester. The present invention discloses an isocyanate production process including specific steps and using a composition containing a carbamic acid ester and an aromatic hydroxy compound, as well as a composition for transfer or storage of carbamic acid ester comprising the carbamic acid ester and the specific aromatic hydroxy compound.

PROCESS FOR PRODUCING ISOCYANATE

An object of the present invention is to provide a process allowing long-term, stable production of isocyanates at a high yield without the various problems found in the prior art during production of isocyanates without using phosgene. The present invention discloses a process for producing an isocyanate by subjecting a carbamic acid ester to a decomposition reaction in the presence of a compound having an active proton and a carbonic acid derivative.
