ABSTRACT:
Lower alkyl, neutral phosphoryl esters are disclosed herein as effective materials to reduce deleterious chloro compound concentrations in polyolefins and compositions based thereon, which polyolefins and compositions are produced in bulk or vapor-phase processes using high yield catalysts in which catalyst residues and solubles need not be removed prior to processing.
