Abstract: A preparation of aryl carbamates can be achieved readily by carbonylation of an aromatic polyamine compound with diphenyl carbonate (DPC) using a combination of an organic acid and a tertiary amine as a catalyst. Aryl carbamate can be converted into 4,4?-diphenylmethane diisocyanate (MDI) by heating it at about 200 to about 230° C. in a non-polar solvent containing inhibitor such as benzoyl chloride. In another application, trans-ureation of biscarbamates with an amine or mixed amines is found to be extremely facile in a polar solvent such as dimethyl sulfoxide (DMSO) and tetramethylene sulfone (TMS) in absence of any catalyst to make polyurea polymers of high molecular weights. Thus, efficient green-chemistry processes based on biscarbamates in making isocyanate products as well as urea prepolymers, urea elastomers and urea plastics have been developed in all in excellent yields without using reactive phosgene or 4,4?-diphenylmethane diisocyanate separately in the trans-ureation polymerizations.

Abstract: To produce an anti-flame film, nanoscale silicate platelets (NSP) are first diluted with water or an organic solvent; the dispersion is then dried on a surface to remove the water or organic solvent and finally an almost inorganic and flexible film with a thickness of 1 to 1,000 ?m is obtained. The film has a regularly layered alignment of primary platelet (1 nm thickness) structure. The NSP film has excellent anti-flame and heat insulation properties that can effectively shield a flame of more than 800° C. without apparent deformation in shape. The NSP can be blended with polymers with a composition over 30% or preferably 70% of NSP to make composite films with significant improvement in flame and heat shielding.

Abstract: This invention provides one-pot reaction for digesting polycarbonate waste with alkylene glycol in the presence of a basic catalyst at 180° C. under normal atmospheric pressure. The digested product mixture was found to consist of bisphenol A (BPA) and monoalkoxylated and bisalkoxylated diols of BPA. Alkoxylation of BPA and monoalkoxylated diols of BPA is performed by adding urea or urea derivative (or carbonic acid ester or amine ester) to the digested product mixture at a high temperature under normal atmospheric pressure to obtain the final product, i.e., bisalkoxylated diols of BPA in high yield. The bisalkoxylated diols of BPA may be used as raw materials to synthesize polymer such as polyurethane (PU) or polyester.
