| Abstract: | Rheokinetic studies of curing of oligodiene-urethane prepolymer with a hydroxyl-containing curing agent at the molar ratio NCO/OH = 1.0 were performed. In the initial step of curing, catalyltic formation of polydiene-urethane follows a second-order equation, whereas the urethane formation step is adequately described by a kinetic equation with an autoacceleration effect. |
