Аннотация:The reaction of direct interchain exchange in a homogeneous blend of linear polymers was modeled numerically using the Monte Carlo method. The evolution of the molecular mass and block mass distributions was studied for two types of initial conditions: a blend of two polymers with Flory distribution and a blend of monodisperse polymers. In the course of the reaction, the molecular mass distribution relaxes to the total Flory distribution, whereas the evolution of the block mass distribution to the Bernoulli distribution is considerably slower. The evolution of the block mass distribution was studied for the first time. At early stages of the reaction, the copolymer (product) composition can differ substantially from the composition of the blend as a whole. The transient molecular mass distributions obtained by the Monte Carlo method agree well with the results of theoretical calculations.
