Stabilizer compositions having a stabilizing amount of at least one co-active agent; an ultraviolet light absorber chosen from orthohydroxyphenyl triazine compounds and/or benzoxazinone compounds; and a hindered amine light stabilizer, are provided herein, along with masterbatch concentrates containing same, and processes for using same for stabilizing polymeric organic materials to protect against light and thermal degradation due to exposure to UV irradiation.

Stabilizer compositions and methods for using same for protecting polymeric organic materials from UV light and thermal degradation

The cycle time of polymer compositions subjected to a rotomolding process is improved (i.e., reduced), while the processing window is simultaneously enlarged through the use of a polymer-stabilizing amount of a processing stabilizer system having at least one chroman-based compound according to Formula V: 

Processing additives and uses of same in rotational molding

Stabilizer compositions having a chroman-based compound according to Formula (V): and their use in processes for stabilizing organic materials subject to degradation and/or discoloration due to the effects from light, oxygen and heat, and in processes for producing articles from organic materials blended therewith, are provided herein.

Stabilizer compositions containing substituted chroman compounds and methods of use

Stabilizer compositions having a stabilizing amount of at least one co-active agent; and a stabilizing amount of any one or more ultraviolet light absorber chosen from an ortho-hydroxyphenyl triazine, an ortho-hydroxy benzophenone, or an ortho-hydroxyphenyl benzotriazole, optionally in combination with a stabilizing amount of a hindered amine light stabilizer, are provided herein, along with masterbatch concentrates containing same, and processes for using same for stabilizing organic materials to protect against light and thermal degradation due to exposure to UV irradiation.
