Stabilized polymers and their preparation. |
摘要 |
<p>Oxidatively stabilized polyolefin polymers containing an antioxidant are made more resistant to loss of antioxidant by converting at least some of the antioxidant comprising a polymer of dicyclopentadiene and a phenolic compound into a form non extractable with cyclohexane. The conversion is preferably by reaction in the melt phase in the presence of a radical initiator. Addition of organotin esters, sulphides, oxides or thioethers reduces the colour.</p> |
