Model of the transition of polymer to a mesophase state
Abstract- it was shown that the structural instability of a polymer crystal can be related to trapping different types of lattice vibrations in nonlinear resonances. The trapping condition is the excess of intramode anhar - monicity over intermode interaction. A model of the transition in polymer ty...

| Summary: | Abstract- it was shown that the structural instability of a polymer crystal can be related to trapping different types of lattice vibrations in nonlinear resonances. The trapping condition is the excess of intramode anhar - monicity over intermode interaction. A model of the transition in polymer type polymetil-metacrilat was constructed. It is shown that a coherent state of orientational vibrations of heavy atomic groups are formed below the transition point. It was established that the structural instability of the polymer crystal is the second- order phase transitions. |
