Abstract: A process for the batch or continuous anionic polymerisation or copolymerisation of styrene or diene monomers with alkali metal alkyl as initiator is claimed. The polymerisation is conducted in the presence of a bivalent or higher metal alkyl or aryl (I).

Abstract: A faint-smelling, light-, heat- and/or air-oxygen-stabilised moulding material made of at least one styrene homopolymer or copolymer or acrylate or methacrylate polymers contain stabilising amounts of for example 0.01 to 1 % by weight alpha-tocopherol and 0.1 to 2 % by weight of an organic phosphite, in a quantitative ratio between alpha-tocopherol and phosphite from 1:1 to 1:4, and preferably 0.01 to 2 % by weight of a sterically hindered phenol. The percentages by weight refer to the polymer fraction. The organic phosphite is in turn stabilised with up to 5 % by weight (in relation to the phosphite weight) of an amine or alkanolamine.
