    摘要: 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##

    摘要: Titanocenes with silylated .pi.-cyclopentadienyl ligands in which one or two carbo- or heterocyclic aromatic rings are bonded to the titanium, the aromatic rings being substituted by fluorine, --CF.sub.3, --C.sub.2 F.sub.5, --CF.sub.2 CL or --CF.sub.2 CH.sub.3 in at least one of the two ortho-positions relative to the metal-carbon bonds, are suitable as photoinitiators for the photopolymerization of ethylenically unsaturated substrates. They are distinguished by a high sensitivity, stability to air and the action of heat, and a high activity in the region of UV light to visible light. They are furthermore readily soluble in the photopolymerizable compositions.

    摘要: Light-stabilized polymer microparticles, which contain at least one light stabilizer and free epoxy groups, and processes for the preparation of these microparticles by polymerization of suitable monomers, at least one of these monomers being an epoxide which contains at least one further reactive group, and at least part of the polymerization being carried out in the presence of at least one light stabilizer, are described. The polymer microparticles can be used in coating compositions which comprise a disperse phase, containing these particles, and a liquid continuous phase.Coatings and paints based on the compositions according to the invention are distinguished by improved weathering resistance, in particular high light stability.
