titleOfInvention | Polymeric stabilizer compounds and process for their preparation |
abstract | Polymeric stabilizer compounds are formed by an organic polymeric matrix, of paraffinic character, deriving from a hydrogenated polydiene and bearing bonded at at least one chain end a sterically hindered aminic function. Such polymeric stabilizer compounds are obtained by means of a process, which provides: (a) the polymerization of a diene, by the technique of the living polymers, under the influence of alkyl metal-alkyl or alkyl metal-aryl catalysts, to yield a polydiene bearing on its chain end a terminal metal atom; (b) the reaction of said metal-bearing polydiene with a sterically hindered aminic compound, bearing in its molecule an electrophilic group, in particular a carbonyl group, reactive towards said metal of the metal-bearing polydiene; (c) the catalytic hydrogenation of the polydiene bearing said sterically hindered aminic function at its chain end. The so-obtained compounds are particularly useful in the stabilization of polypropylene towards the U.V. light degrading action. |
