Title: Polymerization method for preparing block copolymer by inserting alkylthioether into bis(tri)thiocarbonate-terminated polymer by alkali-assisted catalysis
Inventor: ZONG LISHUAI
IPC: C08G75/06
Filed: 2019-01-24
Abstract: A polymerization method for preparing a block copolymer by inserting alkylthioether into a bis(tri)thiocarbonate-terminated polymer by alkali-assisted catalysis. An organic base is added as a cocatalyst to form a catalyst system with a reported phase transfer catalyst such as tetraphenylphosphine chloride and tetraphenylamine chloride; and the catalyst system catalyzes a thioester terminal group-containing template compound or polymer and a cyclic thioether-containing monomer to undergo insertion polymerization, so as to obtain a high-molecular-weight homopolymerized or block copolymer. The polymerization method has the beneficial effects that for an insertion reaction initiated by a template compound, the monomer conversion rate is increased to 80% or more; and when the molecular weight of the template polymer is greater than 2500 g/mol, insertion polymerization may still be successfully carried out, and the monomer conversion rate is greater than 80%. The block polymer synthesized by the method has a special phase topological structure, may greatly improve the amorphous state of a polymer, and has a wide application prospect in the fields of self-healing materials, intelligent materials, self-assembly, biopolymers, drug sustained release and the like.
