摘要: The polymerization of 4-methyl-2-pentyne and 1-trimethylsilyl-1-propyne initiated by catalytic systems based on niobium pentachloride Et3SiH, Bu4Sn, Ph4Sn, Ph3SiH as cocatalysts has been investigated. Direct evidence for the living with NbCl5-Ph4Sn system is derived. These are linear molecular mass dependence conversion continuation chain propagation after introduction a new monomer portion.
