摘要: Abstract Polyolefins attract considerable attention due to their vast consumption and wide application. In this study, cross-metathesis polymerization (CMP) is demonstrated be an efficient feasible method for the synthesis of aliphatic polyketones. The synthetic route features good yield, mild condition easy operation. success CMP relies on high tendency between α-olefin vinyl ketone units monomer 2. Optimization was conducted generate unsaturated polyketone P0 (Mn,GPC = 14 kDa), results kinetic study verified efficiency structural integrity system. Furthermore, post-polymerization modification by using thiol-Michael chemistry furnished functional polyketones P1–P6, full conversion internal groups observed in each case. pristine P0–P6 were virtually soluble most common organic solvents. particular, hydrophobic fluorescent (P5 P6) also obtained means. Therefore, strategy shows promising future exemplifies huge potential a diverse range
