标题 :Aliphatic polyimides from a 1:2 molar ration of diamine and unsaturated monoanhydride or unsaturated diacid
发明人：DUAN YANNAN; AVAKIAN ROGER W
权利人:POLYONE CORP
摘要:Aliphatic polyimides are synthesized by a 2:1 molar ratio reaction of an unsaturated monoanhydride or an unsaturated diacid with a diamine. Bio-derived monomers are particularly useful in the synthesis of the aliphatic polyimides.

标 题 :Phenolic ester synthesis
发明人：BURTON LESTER P J
权利人:ETHYL CORP
摘要:A process which enhances conversion and speeds the reaction rate for the preparation of esters. Methyl acrylate and a hindered phenol are reacted (i) in the presence of an alkali metal alkaline catalyst that provides a phenolate anion and (ii) in the presence of an agent which solubilizes the phenolate to enhance the reaction rate. Excellent yields of methyl ester are obtained in a rapid reaction and by-products are minimal. The invention includes a preparation of methyl beta -(3,5-dialkyl-4-hydroxyphenyl)propionates by reaction of a hindered phenol with methyl acrylate in the presence of an alkaline catalyst and dimethyl sulfoxide present in an amount sufficient to advance the reaction rate.
