Definitions
- the present disclosure relates to tellurium-containing compounds, polymers, and methods for producing polymers.
- the radical polymerization reaction is widely used industrially because it has excellent monomer versatility and can be easily performed even in a polar medium such as water.
- the control of the molecular weight by a general radical polymerization method is limited, and the molecular weight distribution of the obtained polymer tends to be wide.
- the living radical polymerization method has attracted attention as a polymerization method for obtaining a controlled molecular structure, and various polymerization control agents have been developed.
- the living radical polymerization method is a polymerization method in which the radical polymerization rate is controlled by reversibly protecting the growth radical with a protecting group which is a dormant species, whereby the molecular weight distribution can be controlled.
- Patent Document 1 describes a living radical polymerization method for producing a haloolefin polymer or a copolymer by radically polymerizing a specific haloolefin in the presence of a specific organic tellurium compound. This method is based on a method called a TERP (organotellurium mediated living radical polymerization) method.
- TERP organotellurium mediated living radical polymerization
- the branched polymer has various properties different from those of the linear polymer. For example, since the branched polymer has a large number of terminal groups, when used as a molding material, the crosslink density of the molded product can be increased and the curability can be improved. Branched polymers are also known to have lower intrinsic viscosities and lower glass transition temperatures than linear polymers. As described above, the branched polymer has unique properties different from those of the linear polymer, and its industrial usefulness is high.
