| 摘要 |
<p>Solid polymeric stabilizer compounds are formed by an organic polymeric matrix, to which linked are groups containing a sterically hindered aminic function, the organic polymeric matrix being a polymeric matrix of a vinyl-aromatic, aromatic with heteroatoms, dienic or olefinic character, containing hydrogen atoms replaceable by metal atoms, the groups containing the sterically hindered aminic function replacing, at least partially, said replaceable-by-metal hydrogen atoms of the matrix.</p><p>Also disclosed are the processes for the preparation of said solid polymeric stabilizers and the stabilized polymeric compositions comprising an organic polymer and a stabilizer amount of said solid polymeric stabilizers.</p> |
