Abstract

A method for preparing a thermoplastic polyoxazolidone, the method including catalytically reacting one or more aromatic diisocyanates and one or more diepoxides, wherein the one or more diepoxides comprise one or more 2-phenylpropane-1,3-diol diglycidyl ether derivatives. The one or more diepoxides further contain one or more diglycidyl ethers of aromatic diols.
