Abstract: This invention relates to divinyl epoxy ethers having the formula ##STR1## wherein x and x' are integers each having a value of from 0 to 3 and to the preparation and use of the above divinyl epoxy ethers for metal, wood or plastic coatings which possess high resistance to solvents and improved flexibility over saturated epoxy compounds.

Abstract: The subject of the invention is an improved process for the industrial scale preparation of the compounds of the formula ##STR1## and salts thereof by acylating the hexitols of the formula (II) with an anhydride of the formula (II) at a temperature of 0.degree.-30.degree. C. in the presence of an organic base and a catalyst of the formula (IV) in a dipolar-aprotic or aprotic solvent.

Abstract: The invention is a process for the preparation of halohydroxyalkyl carbamates which comprises contacting an epihalohydrin carbonate with a secondary amine-containing compound, wherein the secondary amine has a pKa at which the secondary amine will react with the epihalohydrin carbonate and which does not catalyze the formation of unwanted by-products in the further presence of an acid scavenger capable of forming a salt with the hydrogen halide by-product formed, in an amount sufficient to prevent the formation of unwanted by-products, in a polar organic solvent under conditions such that a halohydroxyalkyl carbamate, wherein the carbamate nitrogen is tertiary, is prepared.

Abstract: Aromatic mono or polycarboxylic acid glycidyl esters are obtained in good yields and high purity by transesterification of the corresponding aromatic carboxylic acid alkyl esters with glycidol in the presence of weakly toxic catalysts, namely the alkali, ammonium, and alkaline earth metal salts of pseudohalogen hydride acids with readily polarizable anions.

Abstract: What is disclosed is a method for the transesterification of lower alkyl esters of .alpha.,.beta.-unsaturated acids such as acrylic and methacrylic acid, with an epoxy alcohol, such as glycidol, which uses 1,4-diazabicyclo(2,2,2)octane as a transesterification catalyst.

Abstract: Reaction of a polyol, acid anhydride and diepoxide, preferably in a single step, yields a prepolymer composition containing a prepolymer containing terminal epoxy and non-terminal, secondary hydroxy groups. Reaction of this prepolymer with a polyisocyanate yields a poly(oxazolidone/urethane) thermoset composition which is essentially free of isocyanurate linkages. The thermoset contains oxazolidone linkages in the backbone of its recurring unit and urethane linkages which are present in a side chain of the unit.
