Abstract
Radical reaction product from 1, 1, 1, 3-tetrachloropropane and 1, 1, 1, 5-tetrachloropentane with ethylene was white wax-like product and its structure was considered to be a graft telomer from infrared absorption spectrum. As this product was considered to be a side reaction product on telomerizaton of ethylene with carbon tetrachloride, comparison of the reactivity with chaint ransfer agents indicated that the reaction was in order of CCl4 >> Cl(CH2CH2)2-CCl3 > ClCH2CH2CC13. Especially, using of greater mole ratio of C2H4/Cl(CH2-CH2)nCCl3 or highly concentrated initiator gave fairly high reactivity for side reaction. However, there was almost no such reaction by using lower concentration of initiator and relatively lower concentration of ethylene. The numerical av. degree of polymerization of graft telomer was changeable in wide range (4-23), especially, the graft telomer from 1, 1, 1, 3-tetrachloropropane was much influenced by the relative concentration of ethylene.
