标 题 :Synthesis of carbamate compounds
发明人:BERRIER JOHN VINCENT
权利人:ROHM & HAAS
摘要:Disclosed is a method for the preparation of carbamate compounds substantially free of by-products; the carbamate compounds being prepared by reacting an isocyanate with a hydroxylated compound in the presence of certain catalysts that increase the rate of carbamylation while decreasing the rate of by-product formation.

发明人:SCHÄFER HARALD; TÜRP DAVID; NEU OLIVER; ERHARDT RAINER; FLOJHAR DANIEL; PAUEN THORSTEN; STEINBRECHER ANGELIKA MARIA
权利人:BASF SE
摘要:The present invention relates to quick-drying, hard-elastic, scratch-resistant and durable two-component polyurethane coating compositions, their use and methods of coating. The coating compositions contain as synthesis components polyisocyanate, hydroxyl-containing poly (meth) acrylate polyol, and certain branched polyester polyols obtainable by polycondensation of hexahydrophthalic anhydride, trimethylolpropane, and optionally other components.
