摘要： Morphology-structure of oriented noncrystalline polyesters has been studied using the parameters changes of the broad peaks in wide angle X-ray scattering (WAXS) with azimuth angles. Twe-dimensional WAXS show that the oriented noncrystalline polyester is made up of long plane-like chains arranged in opposition to each other; and these chains are composed of oriented atomic distances with the chain axes parallel to the drawing direction and are closely arranged into lateral ordering. It is concluded that the arrangements of both interchain and intrachain distances are in good order in the oriented direction, while in other directions, they are arranged nearly at random. This shows that the oriented noncrystalline polymers are materials with their ordered structure varying with directions.
