    摘要： The invention relates to a process for the preparation of conductive polymers or prepolymers and to conductive polymers or prepolymers.The process of the invention consists of reacting a polymer containing ethylenic unsaturations such as a hydroxytelechelic polybutadiene with a silane compound of formula ##STR1## in which R.sub.1 denotes a hydrocarbon group containing at least one heteroatom bearing mobile electrons, such as the oxygen of an ether group, andR.sub.2 and R.sub.3 denote a substituted or unsubstituted organic residue or a group R.sub.1.The polymer obtained is precipitated by the addition of a compound which is not a solvent for the polymer, and is separated from the reaction medium.The polymers obtained have an electrical conductivity which is multiplied by a factor of 10.sup.5 relative to the unmodified polymer.The present invention applies in particular in the field of the polymer industry.

    摘要： New organo-lithium initiators, their synthesis, and their use. The initiators have the formula: ##STR1## in which R" is either a hydrogen atom or a methyl radical; 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=o; and R is an alkyl radical of 1 to 4 carbon atoms.The initiators are prepared by reacting compounds of the formula; ##STR2## with an alkyl-lithium RLi in a non-polar solvent in the absence of any polar solvent or complexing agent.The initiators are used to prepare polydienes of high stereoregularity by reacting with a diene, and the polydiene is used to prepare a three-block or star copolymer by reacting with an anionically polymerizable monomer.
