Abstract
Telomers are prepared by reacting an a -olefinic compound with carbon tetrachloride in the presence of ammonia or an organic amine as principal catalyst; a cupric or ferrous salt may be present as secondary catalyst. Solvents such as alkanols may be used. An example reacts styrene with CCl4 in the presence of triethanolamine, methanol and ferrous chloride to obtain a product containing 7,1% Cl and corresponding to telomers containing an average of 18 molecules of styrene to one of CCl4.ALSO:Telomers or adducts are prepared by reacting an a -olefinic compound with carbon tetrachloride in the presence of ammonia or an organic amine as principal catalyst; a cupric or ferrous salt may be present as secondary catalyst. Specified amines are ethanolamine, isopropanolamine, triethanolamine, triisopropanolamine, tetraethylene pentamine, aniline, N,N-dimethylaniline, N,N-dimethyl-p-toluidine and morpholine. Solvents such as alkanols may be used. In examples the olefinic compound is ethylene, 1-octene, vinyl acetate, styrene and propylene.
