- Abstract
Kinetics of radical telomerization of vinyl acetate (VAc) with CDCl as telogen in the presence of AIBN initiator and ZnCl and Co(acac) as catalysis in bulk and solution telomerization was studied through HNMR and GPC. The telomerization of vinyl acetate in chloroform has indicated a random chain sequence with free radical initiators. Co(acac) catalyst, in this reaction controls the tacticity of the telomer chain. The narrower molecular weight distribution of telomer with its higher yield is predominantly syndiotactic. HNMR study of the microstructure of the telomers revealed that the sequential arrangement of CH and CH groups in telomer is controlled in bulk telomerization by Co(acac) catalyst.
