Agents, polymeric polyvalent

Water-soluble peroxide salts, such as ammonium or sodium persulfate, are the usual initiators. The initiating species is the sulfate radical anion generated from either the thermal or redox cleavage of the persulfate anion. The thermal dissociation of the persulfate anion, which is a first-order process at constant temperature (106), can be greatly accelerated by the addition of certain reducing agents or small amounts of polyvalent metal salts, or both (87). By using redox initiator systems, rapid polymerizations are possible at much lower temperatures (25—60°C) than are practical with a thermally initiated system (75—90°C). 

Polyvalent Ligands as Antiviral Agents. The use of polyvalent ligands to inhibit viral infection is the most extensively studied of all polyvalent interactions. This platform has in fact served as the protot5 ical system to validate the fundamental concept of polyvalent ligands as a new class of polymeric pharmaceutical agents.
