Descrição

Descrição geral

1,3,5-Trimethyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxybenzyl)benzene(HEMA) is an antioxidant that can be used to prevent the oxidative degradation of plastics.[1][2]

Aplicação

HEMA can be used as an antioxidant in the polycondensation of poly(isosorbide maleate-co-succinate) and poly(isosorbide maleate) to prepare biobased based unsaturated polyester.[3] It may also be used in the preparation of water soluble polyesters which can potentially be used as in drug delivery and industrial coatings.[4]
