Abstract: Provided herein are polyamine precursors useful in the manufacture of epoxy resins. Use of a polyamine precursor according to the invention provides an epoxy resin formulation having an increased working time over prior art amines used for curing epoxies. Increased working times translate to the ability to manufacture composites which could not be made using conventional epoxy curing agents, such as composite blades for wind-driven turbines. Such polyamines are also useful in polyurea formulations for lengthening reaction time, thus allowing more flow of applied polyurea coatings prior to gellation.

Abstract: 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.

Abstract: An improved method for the production of polyether polyol compositions is disclosed wherein a polyhydric initiator is oxyalkylated with alkylene epoxides at lower temperatures in the presence of an aqueous ammonia solution. The polyether polyol compositions produced have desirable hydroxyl numbers and low viscosities and are particularly useful in the production of excellent rigid polyurethane foams. In addition to catalyzing the reaction, the nitrogen containing moiety itself undergoes oxyalkylation during the process such that the polyether polyol compositions produced contain, admixed therewith, various alkoxyalkanol amines. The alkoxyalkanol amines having reactive hydroxyl groups and acting as a mild catalyst for the polyolisocyanate reaction need not be removed from the polyether polyol composition. In addition, the alkoxyalkanol amines increase the blending compatibility of the polyether polyol compositions.
