Abstract
There is much anecdotal evidence to suggest that deep cold improves some properties of polymers; those most often quoted are strength, wear resistance and clarity of transparent polymers. However, little scientific evidence has been published to support these claims. To find out if there was in fact any improvement in properties, two common polymers were selected for testing. Samples were deep cold treated and tested for improvements in properties that were known to be weak. Some of the tests showed no significant change. However, the wear of acetal was almost half that of untreated material although the environmental stress resistance of polycarbonate deteriorated.
