Notes:
We present a lattice Monte-Carlo simulation of polymer network formation using the bond fluctuation method. We apply this procedure to simulate the formation of a class of simultaneous interpenetrating polymer networks (IPNs) which has been experimentally studied consisting of one network crosslinked with a trifunctional monomer (PCU) and another crosslinked with a tetrafunctional monomer (the free radical vinyl polymer network). The numerical simulation reveals essentially all features found experimentally for this class of IPNs. The system composition and initial morphology, at least for reactions which are relatively fast compared to the uphill diffusion process causing phase separation, is in good agreement with a mean field [random-phase approximations (RPA)] theory. © 1994 American Institute of Physics.
