Abstract
This invention relates generally to para-tertiary alkyl phenyl substituted pyrimidines and triazines and the use thereof to protect against degradation by environmental forces, inclusive of ultraviolet light, actinic radiation, oxidation, moisture, atmospheric pollutants and combinations thereof. The new class of para-tertiary alkyl phenyl substituted pyrimidines and triazines includes two tertiary alkylated phenyl groups, and a resorcinol or substituted resocinol group attached to the triazine or pyrimidine ring. These materials may, under the appropriate circumstances, be bonded to formulations comprising coatings, polymers, resins, organic compounds and the like via reaction of the bondable functionality with the materials of the formulation. A method for stabilizing a material by incorporating such para-tertiary alkyl phenyl substituted pyrimidines and triazines is also disclosed.
