Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
209 words
A polymeric composition having a controllable degradation rate in sunlight and air comprising (1) a polymer which is a member selected from the group consisting of polymer of an olefin having 2 to 3 carbon atoms and styrene polymers and (2) a two component additive system, the first component of said additive being selected from the group consisting of (a) salts of an organic carboxylic acid with a metal capable of existing in at least two valence states and (b) chelates of a metal capable of existing in at least two valence states with a beta diketone, and the second component of the additive being a benzotriazole of the formula: ##SPC3## wherein R 11 , R 12 , R 13 and R 14 are selected from the group consisting of hydrogen, halogen alkyl, aryl, alkoxy, aralkyl, aroyl and aryloxy groups, said additive system being present in an amount effective to decrease the time of degradation of the polymer under the influence of ultraviolet light, each of said components of the additive system being present in an amount sufficient that the mixture thereof is more effective to decrease the time of degradation of the polymer than a corresponding amount of either member of the two component additive system by itself.
Claim 2
Dependent Claim
