Abstract
Solid polymeric stabilizer compounds are disclosed comprising an organic polymeric matrix, to which are linked 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 polymer, 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. Also disclosed are processes for the preparation of said solid polymeric stabilizers and stabilized polymeric compositions comprising an organic polymer and a stabilizing amount of said solid polymeric stabilizers.
