Popis:	Reinforced network poly(urethane-isocyanurate) materials based on oligomeric poly(propylene glycol), tolylene 2,4-diisocyanate, and a diamine were obtained and studied. The materials were prepared through reaction injection molding using polycyclotrimerization and migration polymerization reactions. The Brinell hardness was measured, and the elastic moduli were calculated from the hardness values of the materials. These characteristics vary from 0.95 to 5.62 kg/mm2 and from 156 to 2559 MPa, respectively. The optimal conditions for network formation (molding temperature regime, pressure, reaction time, and conversion) were determined, and the effect of a reinforcing material on the above properties of the polymers was estimated.
