  • Stabilizers, in particular for thermoplastic polyurethanes
    Patent number: 6995230
    Abstract: The invention relates to stabilizers containing at least two phenolic groups bonded to one another via a connecting radical (II) which is a polyol with a number-average molecular weight of from 75×F g/mol to 250×F g/mol, preferably from 100×F g/mol to 200×F g/mol, in particular from 100×F g/mol to 150×F g/mol, where the term F is the number of phenolic groups in the molecule.
