A titanium dioxide pigment is provided for use in polymeric compositions comprising a pyrogenic titanium dioxide pigment which has been treated with an addition system comprising: (a) an organophosphate/alkanolamine addition product, and (b) a polyol. This invention provides for a novel method for treating a pyrogenic titanium dioxide pigment in order to reduce yellowing when such pigment is incorporated into a polymeric composition comprising adding to such pigment an addition system which comprises: (a) an organophosphate/alkanolamine addition product, and (b) a polyol. |
