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 are disclosed. 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.
