Synthese de polymeres liquides par reaction de telomerisation entre le butadiene et le tetrachlorure de carbone

This abstract deals with the telomerization of butadiene with carbon tetrachloride. By changing experimental conditions (the nature of the catalyst [Cu⁺, Cu²⁺, Fe³⁺, Fe (CN)₆^3?, Fe (CN)₆^4?, Mg], the ratio “r” of the concentration of taxogen to that of telogen, the ratio “c” of the concentration of catalyst to that of telogen) we have obtained chlorinated liquid polymers; their molecular weights range between 208 and approx 70,000. The dispersity of these polymers is calculated to be between 1.4 and 1.6. Addition 1–4 is the most frequent, (>80%). The correspondence between ratios r and c and the average molecular weight is established.
