Polyolefin is one of the most-consumed and most widely used synthetic resins. The incorporation of even a small amount of functional groups would endow polyolefin with polarity

reactivity

adhesiveness

antioxidant and fluorescence properties while maintaining their novel intrinsic properties

thus obtaining functional polyolefin with imperative applications. Post modification is nowadays the essential route to produce functional polyolefin. Suffering from poor control on the reaction process and inevitable side reactions

traditional free radical grafting (FRG) method can only produce ill-defined functional polyolefin with relatively low grafting ratios. Through utilization of new initiators

control on the grafting reactions can be enhanced

resulting in polyolefin with high grating ratios. Owing to its excellent control and diverse functional groups available

C—H activation has now emerged as a powerful tool to synthesize well-defined functional polyolefin. After a brief introduction on new developments on FRG

this review contributes a detailed survey on the advances on synthesis of functional polyolefin

via

efficient C—H activation.
