Abstract
The fifth in a series of reports concerned with the fracture and microstructure of plastics. A detailed study of the structures of polyacetal (Delrin (TRADEMARK)) and polyvinylchloride (PVC) (Boltaron) revealed by thermal and chemical etching techniques is described. The results of a study of the effect of sample thickness on the time to failure in creep and environmental stress cracking tests are also included. Samples of PVC; 3.17 mm (1/8 in), 6.35 mm (1/4 in), and 9.53 mm (3/8 in) thick, were tested and a thickness effect was observed for the samples which failed in the environmental stress cracking mode.
