Abstract
A process for improving the stability of polyolefins, characterized by dispersing purified polyolefin powder in an inert hydrocarbon or in an inert chlorided hydrocarbon, after which 0.01% by weight (relative to polyolefin) is added to the dispersion of a boron compound of the general formula ** (See formula) ** where R1 and R2 can be hydrogen, an aliphatic radical with 2-18 C atoms, cycloaliphatic, aromatic or araliphatic radicals, being heated for 30 minutes to 5 hours, while stirring, at temperatures or undertaken between room temperature and the point of boiling the dispersing agent, then separating the polyolefin from the liquid and subsequently washing it several times with the inert dispersing agent.
