Polymerizable UV Stabilizers: I

Abstract

The UV stabilizers 2-OH-4-allyloxybenzophenone and its oxime were prepared. They were copolymerized with styrene to give copolymers containing 2–8% UV stabilizers. The films were exposed to UV light and tested for any change in the carbonyl index, hydroxyl index, tensile strength, elongation at break and evaporation loss. The stabilization efficiency was evaluated by comparing with similar testing on pure polystyrene.
