Abstract
Polymerizable ethylenically unsaturated monomers, for example chloroprene, styrene and butadiene, are stabilized against granular polymer formation by contact with an amount of the nitrite form of an insoluble, strongly basic, N-containing anion exchange resin sufficient to provide at least 0.001 per cent of the nitrite ion, based on the weight of the monomer. Examples show that the self-propagating polymerization reaction, initiated by seeding either liquid chloroprene or sytrene or chloroprene vapour in contact with liquid chloroprene with a small quantity of activated chloroprene granular polymer, is inhibited by the presence of the nitrite resin in contact with the liquid monomer.
