Abstract
A process for improving the stability of polyolefins, characterized in that purified polyolefin powder is dispersed in an aliphatic alcohol with 1 to 4 carbon atoms, and the dispersion is heated after the addition of 0.01 to 0.1% by weight. Weight (referring to the polyolefin) of an organic peroxide with stirring for 4 to 10 hours at temperatures between 80 and 160º C, the polyolefin is separated from the liquid and subsequently washed several times with the inert dispersing medium.
