摘要

Composition containing a photoreactive, UV light absorbing low molecular weight polyalkylpiperidine and a non-photoreactive, low molecular weight sterically hindered polyalkylpiperidine, a solid masterbatch composition comprising the novel composition, a process for stabilizing a natural or synthetic polymeric or prepolymeric substrates and use of stabilized organic materials in the production various products.
