Synox-3052 is particularly effective in stabilizing alkylene and/or butadiene and/or styrene based polymers, elastomers, adhesives, or modifiers e.g. HIPS, ABS, BR, IIR, emulsion-SBR, solution-SBR, SBR-latices, SBS, SEBS, EPDM, EPM, MBS, MABS, SMA, modified acrylates, hydrocarbon resins, terpene and terpene phenolic resins, rosins and rosin derivatives during processing, and/or aging, alone or while being part of polymer blends based on amorphous and or crystalline materials. Such materials may include, but are not limited to, PC, PET, PMMA, as well as polyolefins, polyamides or polyphenyleneoxides.
