FREMGANGSMAADE TIL FREMSTILLING AF STERISK HINDREDE BIS- ELLER POLYPHENOLER |
| 摘要 |
<p>Sterically hindered bisphenols or polyphenols of the general formula <IMAGE> wherein the substituents are defined in Claim 1, are obtained by reacting sterically hindered 2,4,6-trialkylphenols with acetals or with aldehydes or with cyclic or linear polymers of these aldehydes at a temperature of 60 to 200 DEG C in the presence of an acid catatlyst. The sterically hindered bisphenols or polyphenols may be used, for example, as effective, non-staining, non-toxic and low-volatility stabilisers for natural and synthetic rubbers, plastics and other organic products.</p> |
