摘要： The present invention provides a more economical method of producing multifunctional carbonate resins. It overcomes the disadvantage of using relatively expensive starting material, such as polyglycidyl ethers, that have traditionally been used. The present invention makes use of readily available and inexpensive multi-isocyanate compounds reacted with organic carbonates that contain pendant hydroxyl groups to produce products that contain two or more carbonate functionalities. One form of the present invention is a method for preparing a carbonate urethane compound by reacting a carbonate containing compound that also contains a reactive hydroxyl group with a compound containing at least two isocyanate groups. The reaction is performed in a solvent and in the presence of a base.

摘要： A method for preparing carbonates includes reacting an alkylene oxide with carbon dioxide in the presence of a catalyst and a non-protic solvent. The method further includes having the boiling point of the solvent greater than about 70 ° C., and removing the solvent from the reaction product. The solvent used in the various forms of the present invention can be glyme, diglyme, tetraglyme, cumene, toluene, tetrahydofuran, cyclohexanone, ethylbenzene, aromatic hydrocarbons, or ethers. The catalyst used can be a tetraalkyl ammonium halide, such as tetraethyl ammonium bromide. The alkylene oxide that can be used in the invention can include Bisphenol A, Bisphenol B, Bisphenol F, alkylene oxides that have alkyl substituent groups, alkylene oxides that have aryl substituent groups, and alkylene oxides that contain both alkyl and aryl substituent groups. An essentially solvent free carbonate can be prepared by flash removal of the solvent.
