摘要:
The present invention relates to aqueous dispersions for solid phenolic antioxidants, wherein the antioxidants are dispersed in the aqueous phase with polyvinyl alcohol as dispersing agent. The invention also relates to a process, which comprises stabilising a polymer material against oxidative, thermal or light-induced degradation by adding to the polymer the aqueous dispersion.
