Group transfer radical polymerization for the preparation of carbon-chain poly(α-olefins)
Radical polymerization is a powerful technique for producing a variety of polymeric materials. However, the chain transfer reaction impedes the formation of polymers from many common α-olefins such as propene and 1-butene using this method. Consequently, poly(α-olefins) are predominantly produced via coordination polymerization. To address this limitation, we have devised a strategy involving group transfer radical polymerization (GTRP) to facilitate the radical homopolymerization to access carbon-chain poly(α-olefins). This approach enables the precise construction of a diverse array of carbon-chain poly(α-olefins) with high molecular weights. Furthermore, by using nonconventional monomers, we extend the applicability of this technique to the copolymerization of α-olefins with acrylonitrile, paving the way for the synthesis of copolymers with different monomers. To investigate the properties of the polymers obtained by this method, one of the poly(α-olefins) is studied as an interphase layer material in anode-free Li metal batteries, and the results indicate the potential of the polymer in energy storage applications.
