Abstract (en)
[origin: DE19833095A1] No significant decrease in molecular weight occurs when aromatic polymers are catalytically hydrogenated in the presence of an oxygen containing hydrocarbon and a commercially available standard hydrogenation catalyst containing an VIII subgroup element supported on SiO2, Al oxide or their mixtures, and in which less than 15% of the pores are of size 100-1000 angstrom.
