Method for the synthesis of oligomers and hydrocarbon polymers from hydrocarbon halides,ncharacterized in that the hydrocarbon halides are reacted in an atmospherenargon, in the presence of supramolecular sodium and / or potassium complexes, preferablynobtained by reacting metallic sodium or potassium, or an alloy thereof with complexing agentsncations of these metals selected from the group consisting of macrocyclic crown ethers,ncryptands, linear polyethers and derivatives of these compounds in aprotic solventsnorganics or their mixtures at a temperature of -75 ° C to 35 ° C. |
