Chain-growth polymerization of 2-chlorothiophenes promoted by Lewis acids.
نویسندگان
چکیده
Lewis acids promote the polymerization of several 2-chloroalkylenedioxythiophenes, providing high-molecular-weight conjugated polymers. The proposed mechanism is a cationic chain-growth polymerization, as confirmed by end-capping reactions and a linear correlation of molecular weight with percent conversion. The "living" character of this process was used to prepare new block copolymers.

The condition of oligo-micelle formation of sodium di-isodecyl sulfosuccinate (SDIDS) emulsifier in hydroalcoholic solutions is used to study particle formation of vinyl chloride emulsion polymerization in a batch reactor. The change on micellization behavior was investigated by critical micelle concentration (CMC) and zeta potential parameters. To detect the occurrence of secondary nucleation ...

Boron-moiety-containing aluminoxanes (BMAOs) were prepared from the partial protonolysis of Me3Al using various arylboronic acids. Compared with methylaluminoxane (MAO) generated from the hydrolysis of Me3Al, BMAO prepared from C6F5B(OH)2 and Me3Al induced a higher activity at the same Al/Ti ratio in the Ti-based olefin polymerization catalyst (ansa-Me2Si(Flu)(NBu) TiMe2; 5). The time course of...
