trimethylolpropane
Since 1958, when Celanese made trimethylolpropane available in commercial quan tities, its greatest applicabil ity has been in alkyd coatings and urethane foams. A search of the extensive literature on trimethylolpropane reveals many other applications for this chemical. A few of them, with patent and literature refer ence, are shown below.
Elastomers: The allyloxy ketal of trimethylolpropane is a valuable material for preparing sulfur-curable polyurethane elastomers.
Lubricants: An oil company has found trimethylolpropane tri-n-nonanoate useful as an ingredient in silicone lubricat ing oils to improve lubricity and reduce wear.
Plastics: Polyepoxide-amine compositions based on the triglycidyl ether of trimethylolpropane have setting times that help prevent the formation of cracks and decomposition products in large-volume moldings. This advantage, plus their excellent mechanical strength, make them valuable for tools and molds.
-Fainman, M. Z. (to Standard Oil Company of Indiana) U. S. 2,950,250, August 23, 1960.
Plasticizers: Certain lactone polyesters have the advantages of excellent low temperature performance plus low volatility and high resistance to water and oil extraction. They are light-stable, easily handled and low in toxicity. One such polyester is produced by reacting trimethylolpropane and epsilon-ca pro lactone catalytically, and then acetylating the product. - F o w l e r , G. W., and Carruthers, T. F. (to Union Carbide Corporation) U. S. 2,977,385, March 28, 1961.
-McShane, H. F., Jr., (to E. I. duPont de Nemours &. Company, Inc.) U. S. 2,854,486, September 30, 1958.
Resinous Compositions: Polyurethane wire enamel made with trimethylolpropane has good shelf life and adheres to metal and resins. - C a l d e r w o o d , G. C. (to General E l e c t r i c Company) U. S. 2,916,403, December 8, 1959.

We will gladly send you a list of more than 100 references on trimethylolpropane applications, including suggested reading on urethane technology. Write, on your letterhead, to Celanese Chemical Company, Dept.554-G, 522 Fifth Ave., NeW
Textile Finishes: A polyepoxide produced by reaction of tri methylolpropane with epichlorohydrin can be used to make fabrics both crease and shrink-resistant without adversely affecting other properties.
