Copolymerization of acrylonitrile or other polar monomer complexes with olefins or other vinyl monomer

Grafting Copolymerization of Cationic Vinyl Monomer with Quaternary Ammonium Groups onto Polypropylene

Grafting polymerization was a valuable method for the modification of the chemical and physical properties of polymer surfaces. In this paper, the grafting of cationic vinyl monomer with quaternary ammonium groups, methacryloxyethyltrimethyl ammonium chloride (DMC), onto the isotactic polypropylene (iPP) granule was performed by suspension solid-state grafting process. The techniqu...

Generation of novel polymeric materials and catalyst deactivation pathways in polar vinyl monomer insertion copolymerization

Copolymerization of polar monomers with olefins using transition-metal complexes.

Transition-metal catalysts long ago made it from the laboratory bench to the polymerization reactor. Indeed, they are being used around the world to make more than 70 million tons of polyethylene and polypropylene a year. Transition-metal catalysts give polyolefin producers unprecedented flexibility in process and polymer design. However, there are still new worlds for catalysts to conquer. One...

Staphylococcal Clumping with Soluble Fibrin Monomer Complexes

Clumping reaction, using standard suspension of Staph. aureus Newman D-2-C strain and various substrates, was quantitatively tested. It has been shown that clumping occurs in fibrin lysate containing soluble fibrin monomer complexes unclottable by thrombin. The reaction was positive with staphylococcal strains possessing clumping factor regardless of staphylocoagulase production. Clumping react...
