Abstract
|
We investigate using bond-fluctuation simulations the behavior of crosslinked symmetric binary A-B polymer blends. The variation of the A-B-interaction parameter leads to microphase separation. We study it by focussing on the structure factor which we determine for different crosslink densities and for different values of the A-B-interaction parameter. The structure factor peaks at smaller values of the scattering vector q than predicted by de Gennes. This finding is in line with recent experiments, which, however, could not clarify its origin. We relate the finding to the topological disorder inherent in the network structure, which allows for large deformations during the separation process.
