SCALING BEHAVIORS OF PINNING IN POLYMERIZATION-INDUCED PHASE-SEPARATION

Abstract

A dynamical model for the phase separation induced by polymerization has been developed and studied by Monte Carlo simulations. The model shows a pinning of the structure factor and exhibits scaling relations and exponents. We propose a theoretical argument to predict the pinning exponents, which are in agreement with simulation values. For a different concentration ratio of bifunctional to tetrafunctional monomers, the simulation results are also found to be consistent with the theoretical predictions.
