Resistance to aging of polyurethane elastomers


Polimery 1987, No 11-12, 469


DOI: dx.doi.org/10.14314/polimery.1987.469

Summary

The effect of an accelerated weathering on the changes in relative elongation at break of stabilized and non-stabilized polyurethane elastomer films has been investigated. The changes in chemical structure of polymers during aging have been determined by IR-spectroscopy. A synergetic stabilizing system, comprising an antioxidant and a UV-absorber, has been the most efficient among the additives ex amined.
