| 摘 要： | The isotropy or anisotropy in some physical properties of the ammorphous poly(ethyleneterephthalate) films uniaxially drawn at temperatures above its T_g and then quenched toroom temperature have been studied. Experimental results here presented show that thisamorphous state of high global chain orientation but nearly random segmental orientation,the GOLR state, is nearly isotropic in refractive indices and Young's modulus for smalldeformation, while it is very probably anisotropic in thermal conduction and microwavedielectric properties.
