Photostabilization of polymers |
摘要 |
Articles formed from polymers which are susceptible to degradative attack by ultraviolet radiation are stabilized by the application of a thin continuous layer of an energy transfer agent, which agent does not significantly absorb radiation in the ultraviolet region of the spectrum. The energy transfer agent is a substituted phenol, and the agent is used in amounts of at most 0.4%, by weight, based on the demonstrate prolonged resistance to ultraviolet degradation.
