Multiple Olefin Metathesis Polymerizations (MOMP)

چکیده
Olefin metathesis polymerization, in particularly ring-opening metathesis polymerization (ROMP), has been a popular topic of modern research. Two other types are acyclic diene metathesis polymerization (ADMET) and cyclopolymerization of diynes. To date, there has been no report on a metathesis polymerization utilizing more than one metathesis process. Herein, the concept of multiple olefin metathesis polymerizations (MOMP) is introduced where two or three types of olefin metathesis reactions are used to generate well-defined polymer architectures. In the first half of this chapter, ROMP and ADMET processes are combined to produce highly A,Balternating copolymers. In the second half, a polymerization where ROMP and cyclopolymerization are performed in a domino fashion is disclosed. Finally, a transformation involving all three types of olefin metathesis reaction, ring-opening, ring-closing, and cross metathesis cooperatively and orderly generate only one uniform polymer microstructure.

A straightforward synthesis utilizing the ring-opening metathesis polymerization (ROMP) reaction is described for acid-triggered N,O-chelating ruthenium-based pre-catalysts bearing one or two 8-quinolinolate ligands. The innovative pre-catalysts were tested regarding their behavior in ROMP and especially for their use in the synthesis of poly(dicyclopentadiene) (pDCPD). Bearing either the commo...

We demonstrated tandem ring-opening/ring-closing metathesis (RO/RCM) polymerization of monomers containing two cyclopentene moieties and postmodification via insertion polymerization. In this system, well-defined polymers were efficiently formed by tandem cascade RO/RCM reaction pathway. Furthermore, these polymers could be transformed to new A,B-alternating copolymers via a sequential cross me...
