y utiliaing all speCtra data and dividing them into six groups
in the presence of inverted propylene
a ternary copolymerizaholl model was established to calculate the sequence distribuhon of copolymers prepared with different catalyst systems. The results agree with observed values very well. This model is applicableto case both having and not having inverted propylene in chain. This method notonly can be utilind in calculating the area of peaks and kinetic parameters r1
r2 but also can avoid the difficulties of separating peaks and the errors caused by separtaing peaks reluctantly.
