| Abstract: | This paper uses the second order interaction rotational isomeric state model of the conformational statistics of polymer chains to calculate the probability Pkt of k continuous trans(t) states in the polymethylene (PM) chain at different temperature, and Pkt as the function of temperature and number of the bonds in continuous t states is obtaind in the 150-500K temperature range.It also analyses the particular of the probability of the sequence of trans bonds in the polymethylene chain. It discusses the possibility that the second order interaction rotational isomeric state model is used in polyethylene single crystal forming in the thin solution, which helps to further study the crystal theory. |
