USE OF SUBSTITUTED BIAROMATIC β-DIKETONE AS STABILISING AGENT OF HALOGENATED POLYMERS AND RESULTING POLYMER

摘要

The invention concerns the use of a stabilising composition free of 6-amino-uracyl or 6-amino-thiouracyl derivative, and comprising at least a β-diketone bearing two aromatic rings one of which at least bears a substituent on one of the two ortho position or on the para position; said substituent being selected among the radicals -R, -OR, -SR, -COOH, -O-CF3, -S-CF3, formulae wherein R is an alkyl radical. The invention also concerns halogenated polymers comprising such a stabilising composition.
