Title:
Alicyclic poly phosphite polymer stabilizer
Document Type and Number:
Japanese Patent JP5914758
Kind Code:
B2
Abstract:
Polymeric and copolymeric polyphosphites are described which contain a cycloaliphatic moiety, preferably cyclohexane dimethanol, in the polyphosphite backbone chain. The novel phosphites described herein are suitable for stabilization of organic materials against oxidative, thermal or actinic degradation. At least one advantage of the technology resides in the recognition that phosphites which are based on cycloaliphatic diols such as CHDM, have high percentages of phosphorus and therefore are very effective antioxidants.
