摘要：

Poly(p-2-methoxyphenylene vinylene) (MeOPPV) becomes preferentially oriented when its precursor polymer films are subjected to heating and uniaxial stretching. The orientation of the molecular chains is achieved as a result of both rigid unit formation and the transient plasticization by release of small molecules during stretching. The orientation of the aggregated chains was studied by infra-red dichroism. A high degree of orientation was observed, but the efficiency of orientation by drawing was found to be lower in MeOPPV than reported for poly(p-phenylene vinylene), indicating that the substituted methoxy group gives rise to disorder in the fully converted polymer.
