  • Encapsulated phosphites
    Patent number: 4299885
    Abstract: An improved polymer additive characterized by excellent stability to hydrolysis. Dialkyl pentaerythritol diphosphites are encapsulated in a petroleum or ester wax and thereby rendered relatively immune to decomposition under ordinary conditions of storage. At the same time, the wax coating is sufficiently low melting as to present no problem during milling operations at elevated temperatures, for example, where the heat stabilizing qualities of the dialkyl pentaerythritol diphosphite are required.
