Abstract: A process for stabilising polyethylene grit, in which the latter is treated with a sterically hindered phenol and an ester of phosphorous or hypophosphorous acid, characterised in that the polyethylene grit is mixed with the sterically hindered phenol in liquid, molten form and with the ester of phosphorous or hypophosphorous acid within a ground polyolefin matrix in which the ester has been incorporated, and the polyolefin matrix is compatible with the polyethylene grit.
