This report, in conjunction with that for the previous six months, forms the complete first year report for the period 1st October, 1965 to 31st September, 1966. Detailed results on the stress-strain properties of anisotropic polyethylene and the static fatigue of anisotropic polyvinyl chloride are presented. As detailed studies on the above polymers are still in progress, no detailed analysis of the results is given at this stage.
