    摘要: A polymer composition and a process for preparing the same are provided which composition is degradable under the action of ultraviolet light and/or sunlight and/or thermally and the polymer component of which comprises thermoplastic polymers or copolymers of .alpha.-olefins, or comprises polystyrene. The composition contains a photolyzable metal compound promoting degradation which is present at least partially in the composition in an extremely finely divided state.
