Polymerization

Another polymer characterization technique is Automatic Continuous Online Monitoring of Polymerization Reactions (ACOMP) which provides real-time characterization of polymerization reactions.

For polymerization, the kinetic chain length defined above may differ from the degree of polymerization of the product macromolecule.

Polymerization The abiotic polymerization of amino acids into proteins through the formation of peptide bonds was thought to occur only at temperatures over 140 °C.

Sickle cell disease is an inherited blood disorder caused by a mutation in the beta-globin gene that leads to polymerization of the sickle hemoglobin protein (HbS).

A combination of titanium trichloride and triethylaluminum brings about the polymerization of organic compounds with carbon-carbon double bonds to form polymers of high molecular weight and ordered structures.

A combination of two different initiators is often used to give a uniform rate of polymerization.

After the polymer has grown by about 10x, the short polymer precipitates inside the droplet of VCM, and polymerization continues with the precipitated, solvent-swollen particles.

Alkenes serve as a feedstock for the petrochemical industry because they can participate in a wide variety of reactions, prominently polymerization and alkylation.

All modern supported Ziegler–Natta catalysts designed for polymerization of propylene and higher 1-alkenes are prepared with TiCl 4 as the active ingredient and MgCl 2 as a support.

Also, the polymerization reactions for Nylon 6 and Spandex do not proceed by elimination of water or other small molecules.

An example of alkene polymerization, in which each styrene monomer's double bond reforms as a single bond plus a bond to another styrene monomer.

Because PTFE is poorly soluble in almost all solvents, the polymerization is conducted as an emulsion in water.

Between 1882 and 1906, Fischer determined the structure and also showed that uric acid can be converted to guanine. citation Syntheses Trace amounts of guanine form by the polymerization of ammonium cyanide ( NHmain CN ).

Changing the conditions of polymerization alters the chemical composition of the product and its properties.

Condensation polymerization is occasionally used to form simple hydrocarbons.

During polymerization, the tubulin dimers are in the GTP -bound state.

During the polymerization process, some chemical groups may be lost from each monomer.

During tip growth, cell walls are extended by the external assembly and polymerization of cell wall components, and the internal production of new cell membrane. citation The spitzenkörper is an intracellular organelle associated with tip growth.
