Multiple Olefin Metathesis Polymerization That Combines All Three Olefin Metathesis Transformations: Ring-Opening, Ring-Closing, and Cross Metathesis

, 2016
We demonstrated tandem ring-opening/ring-closing metathesis (RO/RCM) polymerization of monomers containing two cyclopentene moieties and postmodification via insertion polymerization.

Synthesis of Block Copolymers Utilizing Alkoxycarbonylation or Aminocarbonylation of Growing Chain End in Pd‐Catalyzed Living Polymerization of Olefins

Macromolecular Materials and Engineering
Diimine Pd catalysts have been known to promote the living polymerization of olefins. Treatment of the living polyolefin with carbon monoxide followed by the addition of alcohols or amines results in alkoxycarbonylation or aminocarbonylation of the ...

REVERSIBLE COVALENT BONDING FOR OLEFIN POLYMERIZATION AND SEPARATION [PDF]

257 pagesThe formation and breaking of covalent bonds is a fundamental aspect of chemistry. Typical reactions with olefins form or break a bond to produce a desired transformation in an irreversible process in order to drive the reaction to completion ...

Modulating Polyolefin Copolymer Composition via Redox-Active Olefin Polymerization Catalysts

, 2016
The ability to precisely modulate polymer architecture and composition is a long-standing goal within the field of polymer synthesis. Herein, we demonstrate that redox-active olefin polymerization catalysts may be used to predictably tailor polyolefin ...

New Method for Online Observation of Growing Polyolefin Particles

CHIMIA, 2001
In classical experimental research work on catalytic olefin polymerization, kinetics and powder properties are always determined as an average value over a large number of polymer particles.
