Description
Summary:2- tert-Butyl-6-(3- tert-butyl-2-hydroxy-5-methylbenzyl)-4-methylphenyl acrylate (GM, Sumilizer® GM) is known as an effective thermal stabilizer which protects polymers against thermal degradation caused by heat or mechanical stress especially under oxygen-deficient atmosphere. Its unique bifunctional stabilizing mechanism has been reported recently. 1 Further studies on the influences of structural factors of related phenols on oxidative discoloration and thermal stability of polymers has shown that 2-(1-(2-hydroxy-3,5-di- tert-pentylphenyl)ethyl)-4,6-di- tert-pentylphenyl acrylate (GS, Sumilizer® GS) not only has a more effective thermal stabilizing effect than GM but also has much higher resistance to oxidative discoloration.
