Stereospecific Living Polymerization of Hydrocarbon Monomers

Stereospecific carbene polymerization with oxygenated Rh(diene) species.

Polymers bearing polar functionalities are important materials, since they exhibit beneficial properties with respect to adhesion, paint/printability and surface properties. Commercial synthesis of these materials is mainly based on radical processes, which (so far) only allow poor control over the stereochemistry of the resulting polymers. 2 ] Stereo-controlled polymerisation generally require...

Comparison of polymerization of ancrod and thrombin fibrin monomers.

The polymerization of thrombin and ancrod fibrin monomers was studied with a standardized technique that evaluated turbidity changes and protein incorporation into the clot. Ancrod fibrin monomers were found to polymerize more slowly and form less turbid clots (at identical protein concentrations). Changes in ionic strength and pH influences ancrod fibrin monomer polymerization to a greater ext...

Regio- and stereospecific living polymerization and copolymerization of (E)-1,3-pentadiene with 1,3-butadiene by half-sandwich scandium catalysts.

The living isospecific-cis-1,4-polymerization and block-copolymerization of (E)-1,3-pentadiene with 1,3-butadiene have been achieved for the first time by using cationic half-sandwich scandium catalysts.

Highly trans-stereospecific Isoprene Polymerization by Neodymium Borohydrido Catalysts

Title Controlled Polymerization by Incarceration of Monomers in Nanochannels

Recently, Metal-Organic Frameworks (MOFs) or Porous Coordination Polymers (PCPs) composed of transition metal ions and bridging organic ligands have been extensively studied. The characteristic features of PCPs are highly regular channel structures, controllable channel sizes approximating molecular dimensions, designable surface potentials and functionality, and flexible frameworks responsive ...
