    Description / Table of Contents: An Polymethylmethacrylaten, durch Redoxinitiierung in wäßriger Lösung dargestellt, wurden kolorimetrische Endgruppenbestimmungen durchgeführt. Die Redoxsysteme bestanden aus einer Sulfoxygruppe, HSO3-, SO2-3, S2O2-3, S2O2-4 oder S2O2-5 als Reduktionsmittel und einem der folgenden Aktivatoren: (a) Metallionen: Cu2+, Fe3+ und Ag+; (b) Kaliumchlorat und -bromat; (c) Wasserstoffperoxid und (d) Sauerstoff.Als Endgruppen werden im Falle (a) und (b) nur hydrolysebeständige Sulfoxygruppen eingebaut, bei (c) und (d) sowohl Sulfoxy- als auch Hydroxylgruppen.
    Notes: Poly(methyl methacrylate) samples obtained by aqueous redox initiation with reducing sulfoxy compounds such as HSO3-, SO2-3, S2O2-3, S2O2-4, and S2O2-5 in conjunction with different activators are analysed for endgroup content by the application of dye techniques, and limiting conditions for polymerization are reported in specific cases. Activators used are: (a) metal ions such as Cu2+, Fe3+, and Ag+ ion; (b) KCIO3 and KBrO3; (c) H2O2, and (d) oxygen. Endgroups incorporated are only nonhydrolysable sulfoxy in case of (a) and (b), and both nonhydrolysable sulfoxy and hydroxyl in case of (c) and (d).
