Coordination polymerization initiator
The initiators of coordination polymerization are often called coordination (or complex) initiators, montan wax for cars and mainly include Zie-gle r-Natta initiators, x allyl transition metal initiators and alkyl lithium initiators. Among them, Ziegler-Natta initiator has the most types, varied components, and the most widely used. There are also homogeneous and heterogeneous phases. The role of the coordination initiator includes: one is to provide an active species to initiate polymerization; the other is that the remaining part of the initiator (usually a counter ion containing transition metal) provides unique coordination ability next to the initiation center, and this coordination can promote The monomer enters the growth chain in a certain configuration, that is, the monomer can be positioned through coordination. When the coordination bond between the counterion and the growing chain is broken, it is immediately formed between the end of the growing chain and the monomer.
