CYCLIC PHOSPHITES OF POLYALCOHOLS, THEIR MANUFACTURE AND THEIR USE

摘要

of the disclosure: The invention is related to novel phosphites, their use as stabilizers for organic polymers, furthermore to stabilizer compositions containing these novel phosphites as well as the organic polymers stabilized therewith. The novel phosphites have a good stabilizing effect, especially in combination with known stabilizers, and they are substantially stable against hydrolytical influence. Their volatility and tendency to exudation are very weak.
