Halogen bonding organocatalysts (R-Hal-B) facilitated smooth living cationic polymerization of vinyl (R-Cl) monomers at room temperature, producing a good amount of pure yield, opening doors to ...

Vinyl polymerization (polymerization of vinyl compounds) is a useful method for preparing sp 3-carbon-based main-chain polymers including commodity plastics, where the polymer backbone is ...

Controlled/living radical polymerization can be categorized into the following three main process: nitroxide-mediated or stable free-radical polymerization, 24, 25, 26 metal-catalyzed or atom ...

In contrast to the well-known vinyl polymerization, where the main chain is constructed from two carbon units of vinyl monomers such as ethylene and styrene, the polymerization of diazoacetate ...

Traditional polyesters are obtained via ring-opening polymerization (ROP), but significant research is currently directed at designing new biodegradable vinyl polymers with esters groups in the ...

THE nature of the termination reaction in vinyl polymerization, that is, the question of disproportionation or combination of polymeric free radicals, has been the subject of controversy. A number ...

Controlled radical polymerization is a means of manufacturing highly branched three-dimensional macromolecules known as hyperbranched polymers. It might employ inimers, compounds containing an ...

HDPE and LLDPE are made by Ziegler-Natta vinyl polymerization, a method that uses a transition-metal catalyst, like TiCl 3, to initiate polymerization.

In 1912, German chemist Fritz Klatte discovered PVA when he observed that vinyl acetate easily reacts with itself. Klatte’s PVA formulations were dense solids; but over the years, researchers ...

Spectra of CR-39 monomer: A - infrared and B -Raman. and of partly polymerized monomer (ca. 80% consumption of C=C bonds): C - infrared and D - Raman. (This figure was reproduced from O’Donnell and ...
