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.
