摘要： Epoxy-terminated polyoxazolidone having from about 5 to about 30 weight percent of the isocyanate content are described. These polyoxazolidone are prepared by a process in which various process parameters are controlled in a targeted manner to give a product having from about 50 to about 100 percent of isocyanate groups converted to oxazolidone rings and from about 0 to about 50 percent of the isocyanate groups converted to isocyanurate rings. These epoxy terminated polyoxazolidones exhibit high glass transition temperatures and high resistance to chemicals when cured. They are useful for the preparation of electrical laminates, particularly laminates used in the preparation of electrical circuit boards.
