Inside the case of ethylene, the activity increased about two instances, regardless of the level of 1hexene, and in copolymerization with propylene, the activity improved about two.5 to three occasions with rising the volume of 1hexene. The content of 1hexene inside the copolymer samples also elevated with all the boost in 1hexene in the reaction technique. In unique, the 1hexene content of your heptanesoluble element polymer changed significantly, suggesting that the insertion of 1hexene into the polymer chain lowered the polymer crystallinity. It is intriguing that such a adequate comonomer effect was observed for SCat, even though its catalyst overlayer was totally opened from the beginning, with regards to fragmentation. This suggests that diffusion inhibition by the polymer film (barrier effect) also performs at the amount of the primary catalyst particles. Alternatively, when PACat50 was utilized, no comonomer impact was observed for both ethylene and propylene.
