Anion-active sequestrents

Controlled Buffer. By the appropriate choice of ratio of silica to NaOH, one can effectively buffer hydrogen ion activity in the important industrial range of 9 to 11. When systems performance is dependent on anionic surfactants and sequestrants, this property is valued greatly. [Pg.574]

Accelerators These increase the rate of polymerization. They should not be confused with polymerization initiators as they are not sufficiently nucleophilic to induce polymerization. The compounds described in the literature have one common feature, namely, they are all capable of sequestering alkali metal cations. The mechanism by which accelerators function is not clear, but it is believed to involve either increasing ion separation at the growing chain end or activation of anions on the substrate by cation sequestration to give so-called naked anions in the liquid adhesive. Examples of compounds used as accelerators are crown ethers (II), polyalkene oxide (III), podands (IV) and calixarenes (V). [Pg.99]
