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).
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 75xF g/mol to 250xF g/mol, preferably from 100xF g/mol to 200xF g/mol, in particular from 100xF g/mol to 150xF g/mol, where the term F is the number of phenolic groups in the molecule.

Abstract:
The invention relates to a mixture of substances with a number average molecular weight of between 500 and 15000 g/mol, whereby the number average molecular weight is different from the weight average molecular weight which is obtainable by A) reacting UV-absorbers, or a mixture of UV-absorbers and stabilisers for synthetic materials with dioles, whereby at least one section of the UV-absorbers or the stabilisers comprise at least two groups which react against dioles, and/or B) reacting UV-absorbers, or a mixture of UV-absorbers and stabilisers for thermoplastic synthetic materials with a polyol.
Abstract:
The invention relates to catalysts containing the following structural units: at least one tertiary amino group and at least one group which can complex or protonate the amino groups after disintegration.
Abstract:
Thermoplastics comprising plasticizer (i), wherein the plasticizer (i) is based on a polyether having at least one hydroxy group, and the at least one hydroxy group in the plasticizer has been alkylated or has been esterified with a monocarboxylic acid.
Abstract:
Catalysts contain, as structural units, at least one tertiary amino group and at least one group which, after its decomposition, is capable of complexing or protonating the tertiary amino group.
