POLYMERIC SEQUESTERING AGENT

ILs have the potential to overcome many of the problems of associated with current C02 capture techniques. ILs are particularly applicable in absorption of C02 while effectively avoiding the loss of sequestering agents. Other advantage of ILs is that they can be combined into polymeric forms, increasing the C02 sorption capacity compared with other ILs and conventional solvents and greatly facilitates the separation and ease of operation. 

Other Components Other components of emulsion polymerization systems include electrolytes and sequestering agents. Sometimes electrolytes are added to act as buffers and to avoid the hydrolysis of monomers containing the ester group or the acceleration of persulfate initiators decomposition as well [79, 111], It has to be kept in mind that the addition of electrolytes has an influence on the colloidal stability of the latex, CMC, micellar aggregation number, and adsorption of surfactant, as well as on other physicochemical phenomena [25],... 

Silica-based microparticles obtained by the sol-gel process also have limitations that must be known and, when possible, faced. One problem arises with the tendency to gel of the colloidal silica particles formed as a side product in the tetra-alkoxysilane polymerization reaction. In this case, the addition of a sequestering agent or the reduction in the amount of colloidal silicate particles in the suspension leads to aqueous suspensions of silica shell miaocapsules having improved storage stability. ... 

Ethenylidenebis(phosphonic acid) 1 and its esters have found utility as sequestering agents, in the development of polymeric flame retardants, and in certain pharmaceutical appheations. Ethenylidenebis(phosphonic acid) is prepared via the thermal dehydration of tetrasodium (l-hydroxyethylidene)bis(phosphonate) [165], Disadvantages of this time-consuming process include the need for precise control of temperature during the dehydration.
