摘要: Propionaldehyde and sodium perchlorate have a marked effect not only on kinetics of copolymerization propylene oxide tetrahydrofuran (THF) initiated by BF3, also molecular weight characteristics the copolymer obtained. The ability polar compounds to solvate BF3 complexes growing centres slows down all reactions in which they take part. For example, rate isomerization formation cyclic tetramer decreases, while concentration latter during process passes through maximum. This is explained existence chain transfer tetrameter with ring opening.
