Document Type and Number:

WIPO Patent Application WO2002002684

Kind Code:

A9

Abstract:

The invention relates to stabilisers containing at least two phenolic groups which are connected by a polyol, with a number average molecular weight of 75xF g/mol to 250xF g/mol, preferably 100xF g/mol to 200xF g/mol, in particular 100xF g/mol to 150xF g/mol, where the term F = the number of phenolic groups in the molecule, as bridging unit (II).
