The Olin Corporation patent solves the following problem:

Urethane-containing oxazolidone-modified isocyanurate foams containing a relatively large amount of polyurethane known in the art. By way of illustration, US Pat. No. 3,849,349, issued Nov. 19, 1974 to KC Frisch et al revealed that the foams made in a one-step reaction. In its reaction, a polynuclear polyisocyanate having an isocyanate equivalent weight of between 120 and 160, a polyepoxide and a polyol reactions in the presence of a blowing agent and an isocyanate trimerization way. polyol is now to make bubbles in an amount between 15 and 40 percent based on total weight of these three reactants. The foam made according to the patents it contains a significant amount of thermally unstable urethane linkages made to the reaction of a polyol and polyisocyanate, thus making it subject to bubbles in a relatively large amount of heat breakdown in high temperatures.

Our analysis of this patent is as follows:

Olin Corporation’s patent US 4766158 A deals with Urethane-containing oxazolidone-modified isocyanurate foams and a composition and method for their production.
Urethane and oxazolidone-containing isocyanurate foams characterized by cracking resistance and scorching heat resistance and strength at a temperature of about 160 C. or higher. These foams produced by the reaction of at least one polyisocyanate with at least one polyepoxide and at least one polyol in the presence of catalyst, surfactant, and blowing agents.
