Abstract
An oxidized polyethylene wax or other wax in the form of a salt with a metal selected from groups IB, IIB, IIA, IIIA, IIIB, VIB, VIIB and VIIIB of the Periodic Table of the Elements acts as a photoactivator in a polymer composition and degrades the latter. The quantity of the additive can vary from 0.1 to 2.0% by weight, relative to the weight of the composition. The additive can be added directly or, more suitably, via a masterbatch.
