Abstract: Using radical technology in non-polar monomer homopolymerization or copolymerization with functional monomers was summarized.Compared with other polymerization methods,free radical polymerization has the andvantages of facilitated operation,low cost,etc.With the development of controlled/living radical polymerization(LRP),polymer with well-defined structures can be synthesized.When selecting suitable solvent or adding organic lithium salt,α-olefins homopolymerization can be successively carried out under relatively mild conditions.The introduction of Lewis acid or Bronsted acid can significantly increase the content of α-olefins in the copolymer.
