    Abstract: The invention relates to stabilized recycled plastics, which can be obtained from domestic, commercial and industrial waste or valuable material collections, comprising a macrocyclic compounds containing a radical of formula (I) or (II), in the macrocycle or in a side group of the macrocycle, where the macrocycle comprises at least 8 atoms and in which the substituents R, independently of one another, are methyl, ethyl or propyl, or two radicals R on the same carbon atom are, together, a pentamethylene radical, and a is the number 0, 1 or 2. The invention also relates to a process for the stabilization of recycled plastics and to the use of the above macrocyclic compounds as stabilizer. ##STR1##

    Abstract: An increase in the molecular weight of a polyamide or recycled polyamide, essentially without crosslinking, can be achieved by blending said polyamide with a polyfunctional epoxy resin and a sterically hindered hydroxyphenylalkylphosphonic acid ester or half-ester and heating the blend to above the melting point (or the glass transition temperature) of the polyamide, in the absence of a catalyst of the type used in the polymerization of polyamides.

    Abstract: The present invention relates to a process for producing particles which comprise at least one halogen-free flame retardant and which comprise at least one metal oxide or semimetal oxide, where the particle can be a core-shell particle with flame retardant in the core and metal oxide or semimetal oxide in the shell, or a particle in which the distribution of flame retardant and a metal oxide or semimetal oxide is in essence homogeneous. The present invention further relates to particles comprising at least one halogen-free flame retardant and comprising at least one metal oxide or semimetal oxide, to a polymer molding composition comprising said particles and comprising at least one thermoplastic or thermoset polymer, and also to the use of said particles in polymer molding compositions or for providing flame retardancy to polymer molding compositions.
