D. Viduna et al., MONTE-CARLO SIMULATION OF MICELLE FORMATION IN BLOCK-COPOLYMER SOLUTIONS, Macromolecular theory and simulations, 7(6), 1998, pp. 649-658
Short block copolymers in selective solvents (bad for A-block, good fo
r B-block) are modeled by flexible bead-spring chains, where beads int
eract with short range Morse potentials of variable strength. It is sh
own that already very shea chains (N-A = N-B = 2) exhibit a rather wel
l-defined critical micelle concentration (cmc). The mass distribution
of the micelles and their gyration tensor components as well as their
internal structure are studied. It is shown that the relaxation time i
ncreases exponentially with the strength EAA Of the attractive energy
between the A-monomers, and thus frozen-in micelles of medium size are
obtained when E-AA is chosen too large. Our results are compared to s
tudies of related but somewhat different models.
