标题:Direct synthesis of composite materials
发明人：TAYLOR LYNN J
权利人:TAYLOR LYNN J
摘要:There is disclosed an in situ process for the preparation of a composite material consisting essentially of an organic polymer or copolymer having dispersed therein an inorganic oxide or mixture of oxides, said process comprising the simultaneous or sequential synthesis of the organic polymer from at least one non-polymeric organic precursor and of the inorganic oxide or oxide mixture derived from at least one inorganic-oxide precursor.

标题 :Synthesis of polyol bis(allyl carbonate) utilizing reagent recovery and recycle
发明人：YOUNG ELGIN E
权利人:PPG INDUSTRIES INC
摘要:Disclosed is an improved method of forming polyol (allyl carbonate) monomers. In the disclosed method, the organic by-products as diallyl carbonate and unreacted reagents as allyl alcohol are separated from the brine and wash water derived aqueous phase and returned to the allyl carbonate synthesis reaction. The aqueous phase is further separated to recover allyl alcohol therefrom, which is returned to the allyl carbonate synthesis reactor as an azeotrope.

标题:Process for synthesis of allophanate compounds and compositions including the product thereof
发明人：TAZZIA CHARLES L
权利人:BASF CORP
摘要:The invention provides a process for preparing an allophanate-containing compound in the presence of a metal catalyst and a tertiary amine. In a preferred process, the tertiary amine compound also has a hydroxyl group. The hydroxyl group can react with the isocyanate functionality. Also disclosed is a process in which an allophanate-containing compound is prepared with copper acetate monohydrate as a catalyst. The allophanate-containing compound is used as a curing agent in coating compositions, particularly electrocoat coating compositions. The coating compositions are used to coat articles.

标 题:Uncatalyzed synthesis of symmetrical dicarbonates
发明人：FRANKLIN RALPH
权利人:AKZO NV
摘要:A dialkyl dicarbonate is prepared by contacting an alkyl haloformate with an alkali metal carbonate in the presence of a solvating amount of a solvent. The process of the invention does not require a catalyst, is easy to carry out, does not employ particularly hazardous materials, does not require cumbersome purification steps, and provides a high yield of dicarbonate.
