By way of example, a process for producing a polyarylene sulfide may include reacting a material that provides a hydrosulfide ion (e.g., an alkali metal sulfide) with a dihaloaromatic compound in an organic amide solvent.
WebThe polymerization of styrene by amide ion in liquid ammonia, one of the first anionic systems to be studied in detail, is one of the few anionic polymerizations where chain transfer to solvent is extensive [Higginson and Wooding, 1952]. The nonterminating character of living anionic polymerization (LAP) is apparent in several different ways. WebRadical polymerization. 15 languages. Tools. In polymer chemistry, free-radical polymerization ( FRP) is a method of polymerization by which a polymer forms by the successive addition of free-radical building blocks ( repeat units ). Free radicals can be formed by a number of different mechanisms, usually involving separate initiator molecules.
