Abstract: Esterified arylhydroxy compounds for the production of polyurethane or polyisocyanurate. In order to provide aromatic polyols for the production of polyurethanes or polyisocyanurates which are process-technically suitable in terms of their viscosity and at the same time give the end product good physical properties and a good reaction to fire, esterified arylhydroxy compounds are proposed as polyols.

Abstract: A rigid non-isocyanate polyurethane foam and a preparation method therefor are provided. According to the present application, a rigid epoxide is firstly reacted with carbon dioxide to obtain rigid cyclic carbonate, then the product is reacted with diamine to obtain rigid non-isocyanate polyurethane, and the rigid non-isocyanate polyurethane is mixed with a foaming agent for foaming to obtain rigid non-isocyanate polyurethane foam. The present application improves the mechanical property of non-isocyanate polyurethane by optimizing the structures and groups of raw materials; according to the present application, mild reaction conditions such as atmospheric pressure and low temperature are used, and the amounts of reactants and foaming agents are adjusted, so that the reaction is significantly enhanced, and an excellent foaming effect is achieved.

Abstract: Modified lignin products, processes for making them, and their use to produce rigid polyurethane or polyisocyanurate foams are disclosed. The processes comprise heating a lignin source with a nitrogen source and a starved concentration of a C1-C5 aldehyde to give a reaction mixture comprising a Mannich condensation product, neutralizing the reaction mixture, and isolating the modified lignin product. The process is performed at a mass ratio of lignin source to nitrogen source within the range of 1:1 to 1:5 and at a molar ratio of nitrogen source to C1-C5 aldehyde within the range of 3.5:1 to 1:1. Polyol blends and performance additives that contain the modified lignin products are described. Rigid foams that process well and incorporate up to 60 wt. %, based on the amount of polyol component, of the modified lignin contribute to excellent flame retardancy and low-temperature R-value performance.
