Abstract
Filled polyolefin compositions having improved thermal stability characteristics are formed by incorporation therein of an effective amount for improvement of such a characteristics of a di(polyoxyalkylene)hydroxyalkyl phosphonate. In most filled polyolefin compositions, the phosphonate also results in color improvement.
Claims4
A filler material which improves the thermal stability of polyolefin compositions containing it which comprises an inorganic filler and an effective amount for such improved thermal stability of a dipolyoxyalkylene hydroxyalkyl phosphonate having the formula ##STR2## where R, R' and R" are independently C.sub.1 -C.sub.4 alkyl and the sum of m and n is an integer from 2 to 10.
