Abstract
General equations, allowing to calculate the contribution of each fraction (F), ultra-high molecular weight, high-molecular weight, medium molecular weight and low molecular weight of initial rubber SKI-3 in the strength fpi of the rubber based on it after plasticization (P). The equations for fpi are obtained in cases where the initial SKI-3 contained only one F. The dependences of fрi on the value of MM (molecular weight F) and the conditions of P (time t and temperature T) are given. The values of the constant β, which is part of the exponent of the equation connecting fpi with its values before P and MM, depending on T and t, are compared with those used earlier and their close values are shown. The values of the constant Kpi for each F depended on T and t, which is also included in the exponent of this equation, are considered. The influence of the P mechanism on the obtained results is under discussion.
