ABSTRACT OF THE DISCLOSURE "Living" polymers and their preparations from acrylic monomers of the formula CH2=C(Y)X where X is -CN, -CH=CHC(O)X' or C(O)X', X' being defined hydrocarbyl groups or derivatives thereof, and Y being -H, -CH3, -CN or CO2R where R is hydrocarbyl, and/or from hydrocarbyl-substituted maleimide monomers using defined organosilicon, organotin and organogermanium initiators and bifluoride ion co-catalysts are described. The invention provides homopolymers and copolymers of acrylate and/or methacrylate monomers, especially relatively monodisperse copolymers of methacrylate and acrylate comonomers. The polymers may be used in the manufacture of fibres, films and finishes for metal, glass and wood. Case CR-8129B
