Abstract
Certain phosphite-isocyanurate oligomers and their use as thermal stabilizers in polymer compositions. The phosphite-isocyanurates may be prepared from a tris-hydroxyalkyl isocyanurate by reaction with an organic phosphite such as triphenyl phosphite or tributyl phosphite. Optionally, an alcohol such as decyl alcohol may be employed as a reactant.
Claims7
A phosphite-isocyanurate having the structure ##STR3## wherein R is methyl or hydrogen, R.sub.1 and R.sub.2 are alkyl radicals of 10 or more carbon atoms, phenyl or alkylphenyl radicals of 10-22 carbon atoms, X is R.sub.2 or ##STR4## n is 2-10 and Y is R.sub.2 or X.
