摘要

By this Monte Carlo simulation we studied the glass transition of polymethylene using themodified bond-fluctuation model combined with considering the rotational-isomeric state model. Theconfigurational properties in the polymethylene (PM) melts

such as the mean length

the mean energy perbond and the mean square radius of gyration were monitored. We found that the chains cannot be in theequilibrium states after a very long time when the temperature of the dense PM chains decreases to 120 K. As the melt vitrifies

these quantities gradually become independent of temperature in a narrow range.The glass transition temperature Tg depends upon the chain length of PM chains

and extrapolation to (CH)2 gives Tg=212K.The dynamics in the PM melts was also studied.It was found that the diffusion coefficients can be described by the Vogel-Fulcher law and the Vogel-Fulcher temperature Tg is 124K.The method may be used to investigate the glass transition of other real polymer chains.
