http://www.qywt.net/shows/10/75.html WebThe formation of popcorn polymers from olefinic monomers is inhibited by the addition of a N,N1-dialkyl hydroxylamine in which each alkyl group contains up to five carbon atoms. Preferably 0.001-5% by wt. of inhibitor is added to the olefin. The inhibitor is particularly valuable in the recovery of monomers from a butadiene or butadiene-styrene latex by …
WebThe polymer chain growth process is known as propagation, and this will continue until termination of the chain is achieved and the reaction comes to an end. This may come about through undesirable side reactions of radical initiators, unwanted auto-polymerization or, more intentionally, by reacting with an inhibitor. Inhibiting Polymerization
