英文摘要The dynamics and conformational-dependent properties of polyoxymethylene (POM) chains are studied using the modified bond-fluctuation model and the rotational-isomeric state model. In our bond-fluctuation model, a Kuhnian bond includes four carbon-oxygen bonds. Each Kuhnian bond may have different energy, and the Kuhnian bond energy is calculated using the tetrahedral lattice model as it gives a reasonable approximation to the carbon-oxygen backbone bond of the POM chain. Our statistical mechanics properties of chains are in good agreement with the theoretical results. The relaxation times tau(1) increase with chain length N by a power law of the form tau(1)(N) approximate to N-2 in the absence of excluded volume and tau(1)(N) approximate to N-2.16 in the presence of excluded volume, and the diffusion coefficients D behave as D approximate to 1/N in the absence and presence of excluded volume.
