โœฆ Synopsis

A~traet--The dynamics of polymer chains confined in pores are investigated in order to examine the effects of pore structure on the dynamics of the lattice model. The dynamics are studied by calculation of the relaxation times of the autocorrelation function of the first three normal coordinates T k and of the end-to-end vector T R for various widths of an infinite parallel-plate and length of side of an infinite cuboid. It is found that the relaxation times T k and T R obey the scaling law: T ~ (N -1) 2. Comparisons with the dynamics of polymer chains confined in an infinite cylinder are made, and the results are almost the same.

We introduce the parameter of probability of movement and study the dynamics of polymer chains by using the improved body-centred cubic lattice model. The model can approach to simulate the dynamics of real polymer chains. We find that the relaxation times obey the relation TR( ) ~ (N -1)2ยฐ5/P ยฐTs i

The dynamics of polymer chains, such as +-A-BR-BR jX, are investigated by means of the equivalent linear polymer chains, $-A-B'-B'+-X, with the probability p of movement of bead B'. It is found that the relaxation times of the equivalent linear polymer chains obey the relation T,(p) = T,.p -Et, wher
