    Abstract - (Show below) - (Hide below)

    Gives a method of assessing molecular orientation in test specimens of amorphous thermoplastic materials by determining the maximum longitudinal reversion after a specified heat treatment. Applies only to specimens exhibiting predominantly uniaxial orientation, such as bars and dumb-bells in which the orientation occurs along the length of the specimen, or plates in which the orientation is parallel to one of the sides but not suitable for fibre reinforced thermoplastics of cellular plastics.
