Polymer melt, dense different chain models

Simulations of polymer blends or block copolymers involve two rather distinct aspects one aspect is the generation of equilibrium configurations of dense polymer melts and the relaxation of the configurations of individual chains this aspect is not essentially different from simulations that deal with one-component polymer solutions and melts, as treated in other chapters of this book. The work described in the present chapter has used dynamic Monte Carlo methods such as combinations of kink jump and crankshaft rotation algorithms (Fig. 7.5(a)) " or simple hops of effective monomers in randomly chosen lattice directions (in the case of the bond fluctuation model " ) or the slithering snake technique. 52-54,55,80,81 algorithms need a nonzero concentration of vacancies,...
