25 MHz proton-decoupled 13C NMR spectra of isotactic and atactic smaptes polymerized with high effective supported catalyst using diester
C6H4[COOCH2CH(CH32)]2
as inester and (CH2O)3Si(C6H5)2 as outester have been determined. The values of triad and pentad tacticity have been calculated from the expanded spectra of methyl carbon region. The kinetic models of stereospecific polymerization mechanism have been discussed. Machanism of higher tacticity for samples using diester high effective supported catalyst system than using monoester supported catalyst system bave been quantitative explained from theoretical model of three parameters.
