摘要： Rigid, solid, non-cellular, urethane polymer compositions can be prepared which are the reaction product of at least one polyhydric alcohol with at least one organic polyisocyanate in the presence of a low molecular weight urethane modifier adduct which is the reaction product prepared, for instance, by reacting (1) at least one polyisocyanate and at least one monohydric alcohol or (2) at least one monofunctional isocyanate with at least one monohydric or polyhydric alcohol. Said adduct can also consist of mixtures of (1) and (2). Such polymers when prepared in the presence of any catalyst for urethane formation which is a liquid or solid at ambient temperature, set quickly to solid, rigid polymers having a density of at least one gram per cubic centimeter. They can be demolded after combining the materials, without the addition of heat from an external source, within a period of less than one minute to about 15 minutes. By proper selection of the urethane modifier adduct, flame-retardant polymers can be prepared.
