The preparation of LNR involves reacting NR latex with an oxidizing agent, as well as a reducing agent to depolymerize the latex to the desired [M.
Introduced under the Isoplast trademark, this series of rigid thermoplastic urethanes is "live" because the molecules depolymerize in the melt and repolymerize upon solidification.
Besides, it is possible to further depolymerize the lignocresol down to the molecular weight level of dimer by alkali treatment.
The resulting crumb rubber is processed in a hydrocarbon-based solvent at a thermodynamically critical condition to depolymerize the crumb rubber and allow for recovery of oil and carbon black.
Our recent research in rat oocytes showed that high dosage of nocodazole could depolymerize spindle microtubules completely and inhibit migration of the condensed chromosomes, while after low dosage of nocodazole treatment, a partially impaired spindle could still translocate to the cortex (Ai et al.
Beyond this temperature, cellulose begins to depolymerize via transglycosylation, and this is followed by fragmentation of sugar units and the production of non-combustible and combustible volatiles.
Although AOC does not produce the enzymatic machinery to completely depolymerize structural carbohydrates to simple sugars, it does produce enzymes that cause partial depolymerization (Boing, 1983) and it aids rumen cellulytic bacteria in completing the depolymerization of cellulosic material to simple sugars (Autrey et al.
This patent relates to advanced plant cell wall degradative systems, specifically enzymes that bind to and/or depolymerize cellulose.
11,12) Microbes in composted sewage sludge are able to depolymerize silicones including cyclosiloxanes to dimethylsilanediol: thus, both biotic and abiotic mechanisms for silicone depolymerization have been demonstrated.
Chitosan will gradually depolymerize to release N-acetyl-b-D-glucosamine, which initiates fibroblast proliferation and helps in ordered collagen deposition and stimulates increased level of natural hyaluronic acid synthesis at the wound site.
3,4] There have also been various attempts to depolymerize the plastics to their monomers, so that the monomers obtained can be used again to produce virgin polymers.
The main constituent of microtubules is tubulin, a globular protein comprising alphaand beta- subunits that is known to depolymerize at temperatures below 10[deegrees]C in most animals.
