Abstract
A phosphite and stabilized thermoplastic composition comprising the phosphite where the phosphite has the formula: ##STR1## In the above compound, R.sup.7 and R.sup.8 are preferably alkyl of from 1 to 6 carbon atoms, most preferably an unsubstituted alkyl group. R.sup.9 is preferably alkyl of 1 to 12 carbon atoms. m is from 0 to 5. The dicumyl group includes the OX groups which are the phosphite portion. The OX group is hindered by only one alkylaryl group at the ortho position with the other ortho position being occupied by hydrogen. X has the following formula: ##STR2## wherein R.sub.2 is independently selected from the group consisting of alkyl groups having from 1 to 12 carbon atoms. z.sub.1 and z.sub.2 can be 0 or 1. R.sub.3, R.sub.4 and R.sub.5 are independently selected from the group consisting of hydrogen, halogen, or alkyl of from 1 to 3 carbon atoms.
