The microstructure of the polymer chains has been studied by 13 C NMR. A high proportion of isolated vinyl units has been found only if the percentage of vinyl is less than 70%, whereas the vinyl sequences are atactic. During the functionalization, if lithium is utilized as catalyst, only...
The adducts and bi-adducts of the reaction of vinyl chloride with carbon tetrachloride, CCl3(CH2CHCl)nCl and Cl(CHClCH2)CCl2(CH2CHCl)pCl respectively, have been studied by 13C and 1H NMR. The identification of the characteristic peaks of each product enables of much better control of the...
