Abstract
The addition of a minor amount of distearyl pentaerythritol diphosphite to olefin polymers containing 2-hydroxy-4-n-octoxybenzophenone as the ultraviolet stabilizer increases the ultraviolet resistance of the polyolefins. Olefin polymers containing these stabilizers can be used in the production of items that will be brought into contact with food products.
