USE OF A MELAMINE BASED COMPOUND AND A HALS COMPOUND AS HEAT STABILIZER IN POLYMERS

摘要

The present invention relates to the use of a composition comprising a) at least one Melamine based Mannich compound of the formula (I) and/or their dimers or trimers and/or one or more precondensate therefrom of the formula (II)and b) at least one hindered amine light stabilizer (HALS) as heat stabilizer, in particular long term heat stabilizer in thermoplastic polymer, preferably in polyolefins.
