It is shown that the system TiC14-(C2Hs)2AICI-(C6Hs)2Mg is highly efficient and very promising as a catalyst of the filling of polyethylene during the polymerization with inorganic fillers (chalk, marble powder, perlite, kaolin and dolomite). The preliminary activation of the filler, the formation t

✦ Synopsis
Experimental results obtained when studying the kinetics of ethylene polymerization in toluene, as well as data on fractionating polyethylene, are analysed and compared with the results of theoretical consideration of molecular weight distribution on the basis of the proposed kinetic scheme.
The constants of the reactions of propagation, initiation, transfer and termination of polymer chains are evaluated and compared with literature data.
