Now I activate the Magic Card-- Polymerization.
Maybe the polymerization process distorted the sample somehow.
Picture 1: A new way to improve the polymerization of PLA(source InnoREX).
Initiation of polymerization due to sonochemically created radicals(polymerization kinetics).
Ultrasound induces and promotes the chemical reaction for the polymerization of latex.
To apply on nail plates polymerization gel- a basis of art composition.
The polymerization is induced by the reaction of a photoinitiator molecule(PI), with the light photons generated by the DMD chip.
From above we powder it with acryle powder, we send a marigold for polymerization, we brush away the remains of powder a brush;
To make them into a drug-delivery system, polymerfilms containing the glaucoma drug are added to the lenses via ultraviolet light polymerization.
On the other hand, materials that tend to shrink during polymerization will draw two adjacent components together and will thus cause breaks or shorts.
Glycolic acid is a useful intermediate for organic synthesis, in a range of reactions including oxidation-reduction, esterification,and long chain polymerization.
Organic catalysts have been shown to efficiently control the polymerization of lactide, but their activity must still be improved to meet industrial standards.
Chemical aggregates of this type are used inperiodic processes with small volumes of production,long reaction times or where better selectivity is achieved, as in some polymerization processes.
Ultrasonically assisted miniemulsion polymerization is applied to various processes- from the encapsulation of inorganic particles to the synthesis of latex particles.
Picture 2: Process setup with ultrasound,microwave and laser to achieve a ring opening polymerization avoiding the use of metal-containing catalysts(Source: InnoREX).
The volume shrinkage of the polymer during polymerization or solidification is caused by the van der Waals force between the monomer molecules in the liquid state or the uncrosslinked long-chain molecules, and the distance between the molecules is large;
The current production process ofPLA requires metal-containing catalysts to improve the polymerization rate of the lactones, which are hazardous to health and environment.
Electron-beam curing is a method of curing paints and inks without the need for traditional solvent. Electron-beam curing produces a finish similar to that of traditional solvent-evaporation processes,but achieves that finish through a polymerization process.
Low-quality devices aren't capable to give thesufficient length of a light beam that there was a polymerization of the covering applied on a nail though to heat and slightly are capable to dry shellac.
After the agglomeration mechanism of sludge including the aluminum ion was analyzed, the group discovered that when there is a high concentration of aluminum ions, after roughly 100 minutes a Keggin-type tridecameric cluster(K-Al13) is formed,and after a few months polymerization occurs.
Thereby, metal-containing catalysts such as tin(II) 2-ethylhexanoate,which is in conventional extrusion processes required to raise the polymerization rate of the lactones to an acceptable efficient level, can be avoided.
The extreme conditions inside collapsing bubbles produce highly reactive species that can be used for various purposes, for instance,the initiation of polymerization without added initiators. As another example, the sonochemical decomposition of volatile organometallic precursors in high-boiling-point solvents produces nanostructured materials in various forms with high catalytic activities. Nanostructured metals, alloys, carbides and sulfides, nanometer colloids, and nanostructured supported catalysts can all be prepared by this general route.”.
Three alternative energy sources- ultrasound, microwave and laser irradiation- are combined to induce the ring-opening polymerization to ensure the high molecular weight polymerization.
In an alcoholic liquid,ultrasonication causes an acceleration of oxidation, polymerization, and condensation of the alcohol, aldehydes, esters, and olefins to build new compounds which create more and better flavor and bouquet.
It should be noted that use of conventional conformal coatings, even if it does not lead to tearing and/or lifting of components,introduces stresses into them during polymerization and is liable to cause changes to their electronic/ mechanical characteristics.
Concerning the problematic nature of catalyst utilization and the growing demand for biobased polymers,the InnoREX project focuses on the development of a polymerization process, in which the conventional metal containing catalysts is replaced by an organic catalyst and assisted by the alternative energy sources of high power ultrasound, microwave and laser.
The characteristics of these molecular sieves include fast adsorption speed, frequent regeneration ability, good crushing resistance and pollution resistance. These features can improve both the efficiency and lifetime of the sieve. 3Å molecular sieves are the necessary desiccant in petroleum andchemical industries for refining oil, polymerization, and chemical gas-liquid depth drying.
Experts recommend to buy only qualitative models of known brands as cheapcope with a task badly, and time spent on polymerization of a covering leaves as much, as when drying by UF-lamps, and happens that shellac doesn't stiffen at all.
Small droplets generated by the application of high shear(ultrasonication) and stabilized by stabilizing agents(emulsifiers),can be hardened by subsequent polymerization or by temperature decrease in the case of low-temperature-melting materials.
After these discoveries Carothers' team was made to shift its research from apure research approach investigating general polymerization to a more practically-focused goal of finding one chemical combination that would lend itself to industrial applications.
