Abstract

The possibility of synthesizing poly(AN-co-VA-co-AMPS) fibre-forming copolymer in a 51.5% aqueous solution of sodium thiocyanate is demonstrated. Slowing of the rate of polymerization occurs when MAA is replaced by its isomeric analog VA as a result of “pseudostabilization” by the VA units of active free-radical polymerization sites.
