| titleOfInvention | Method for synthesizing renewable TPEs (thermoplastic polyurethanes) through FLP (flash polymerization) catalysis based on bifunctional phosphine base |
| abstract | The invention relates to a method for synthesizing renewable TPEs (thermoplastic polyurethanes) by FLP (cyclic FLP) catalysis based on bifunctional phosphine base, belonging to the technical field of polymer synthesis, wherein a vinyl polar monomer is used as a monomer raw material in an organic solvent, and conjugated addition polymerization is carried out under the concerted catalysis of Lewis acid and Lewis base, wherein the molar ratio of the monomer to the Lewis acid to the Lewis base is 15-40000: n:1, the reaction temperature is-78 ℃ to 110 ℃, and the reaction time is 10 seconds to 100 hours. The bifunctional phosphine base initiator adopted by the invention can not only improve the efficiency of synthesizing the segmented copolymer, but also solve the problem that some monomers are difficult to synthesize the triblock copolymer due to great difference of polymerization activities. |
