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)2Β°5/P Β°Ts i
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
We introduce a model of anharmonic polymer chains based on n replicas of the Lie algebra U(2) and find its spectrum and transition rates up to two quanta of vibration. We compare the corresponding formulas with the infrared spectra of n-paraffins.
## Abstract A heterogeneous lattice model for mainβchain liquidβcrystalline polymers is proposed. Phase transition parameters and statistical properties of the chain in the ordered phase are treated in the framework of a meanβfield approximation. The order parameters for the mesogen and the spacer
