The application of the quadratic acid amides of the synthetic materials such as stabilizers for collecting zone, shaped or not

摘要

P the invention relates to a particular application of the bis - amides of the quadratic. / p & & p & according to the invention, it is used for these bis - amides and in particular the 1,3 -, - amides, as stabilizers for synthetic materials selected, provided or not, at a rate of 0,01 to 5% by weight. / p & & p & the compounds are used to stabilize, in particular against the action of the light, and they retain their good mechanical properties, the raw materials or shaped articles based on products of the homopolymerization or copolymerization of olefins and diolefins, of vinyl acetate, ether - esters of urethane, of isocyanurates or acrylonitrile, or of the products of the homopolymerization or grafted polymerization of styrene or its homologues or of vinyl chloride, or homopolyamides, copolyamides or polyethers - amides, as well as of the polyether - amides and of polyether - esteramides. / p
