KINETICS OF PHASE-SEPARATION IN THE PRESENCE OF 2 DISPARATE ENERGY SCALES
PHYSICAL REVIEW LETTERS 70 (21): 3275-3278 MAY 24 1993

View Abstract
We develop a dynamical model for phase separation in a system with two disparate energy scales. Monte Carlo computer simulations of this model reveal a ''pinning'' of the structure factor during spinodal decomposition that obeys new scaling relations. We propose a mechanism for the pinning which allows us to predict exact values for the pinning exponents. Finally, we discuss our model in light of recent experiments.

PHYSICAL GELS AND MICROPHASE SEPARATION IN MULTIBLOCK COPOLYMERS
PHYSICA A 201 (4): 482-495 DEC 15 1993

View Abstract
We present computer simulation results of a solution of multiblock copolymers, and show that a network can form under certain conditions. This network formation is due to a bridging effect, which exists for multiblock but not for diblock copolymers. Because of this special property, we suggest that multiblock copolymers may be used quite generally to describe physical gels. Further, we find that separation of block types from each other hinders phase separation of polymers from solvent when the solvent is poor for both block types.
