Abstract: Abstract A set of ethylene-propylene (E-P) has been copolymerized by asymmetric metallocene catalysts i.e. silylene-bridged rac-Me2Si(2-Me-4-Ph-Ind)2ZrCl2 (SiPh) and ethylene-bridged rac-Et(Ind)2ZrCl2 (EBI) and cocatalyzed with triisobutylaluminum(TIBA)/ borate [Ph3C][B(C6F5)4] under similar conditions for different desire time. Quenching… read more here.

DOI: 10.1039/d2ra01264b
Abstract: Copolymerization of ethylene (E) with 5-vinyl-2-norbornene (VNB) catalyzed by ansa-metallocenes allows the precise control of essential polymeric properties such as comonomer incorporation, molecular weight (Mw), and polydispersity (Đ). Significant efforts have been devoted to synthesizing… read more here.
