New organo-lithium initiators, their synthesis, and their use. The initiators have the formula: <IMAGE> +tr <IMAGE> IN WHICH R'' is either a hydrogen atom or a methyl radial; either n is 1, in which case R' = H and m and p are integers, the sum of which is between 0 and 10 inclusive, or n is 2, R' then being an alkyl radical of 2 to 8 carbon atoms and m = p = 0; and R is an alkyl radical of 1 to 4 carbon atoms. |
