概要
- 論文の詳細を見る
Intra- and interrnolecular interactions in nylon 66 crystal are calculated rnainly trsing internalrotation and Lennard-Jones potential functions reasonably strpposing that the amide planes arefixed and the hexarnethylene moiety in the chain has an inversion center. Partition function isformularized on the basis of sum of the intra- and intermolecular interaction potentials in analogywith the Ising model on a rectangular lattice with degeneracy of interaction energy to show thatthe first-order phase transition occurs when the transition temperature T. is lower than thecritical temrerature Tc and the second-order rhase transition does when V't = T., where T. onlvdepends on the intermolecular interaction and It on the intrarnolecular one mainly. The pressureeffect on this phenomenon is qualitatively explained from temperature- or Ad ((7100 - (17110,010)-dependence of T. and T(.
