摘要：

Polymers with narrow polydispersities were obtained from ROMP initiator when commercially available phosphines were included. Similar to controlled radical polymerizations, it was shown that enhanced control is related to a fast, dynamic equilibrium that exists between dormant and active species and is mediated by the type and quantity of phosphine employed.
