摘要： Oxazolidinones are prepared by reacting an organic isocyanate such as toluene diisocyanate with a vicinal epoxide such as the diglycidyl ether of p,p''-isopropylidine diphenol in the presence of a phosphonium catalyst such as tetrabutyl phosphonium bromide. The oxazolidinone compounds prepared herein are known to be useful as chemical intermediates and in the manufacture of resins and plastics.

摘要： A molding compound consisting essentially of 0.1 to 10 percent of N-methyl-2-pyrrolidone and a resin selected from the group consisting of epoxy, phenolic and silicone resins. The compound is injected in the mold as in the standard molding process and reacts with any surface contamination that may remain from the previous injection. The contamination is thereby removed with the removal of the molded device and the process is essentially self-cleaning.

摘要： An epoxy resin composition which is useful for encapsulating materials which are sensitive to shock, extreme temperature or chemical attack in which an epoxy resin is cured by the use of a curing agent comprised of an anhydride which is partially reacted to the corresponding half ester by reaction with a polyol under catalysis with a uranyl salt. The anhydride, anhydride half ester uranyl salt mixture forms a storable curing agent capable of promoting the complete cure of epoxy resin compositions in short time periods at temperatures of 170*F or less.
