STABILIZED MONOMER COMPOSITIONS |
摘要 |
A process for stabilizing an ethylenically unsaturated monomer or oligomer from premature polymerization is disclosed whereby a stabilizing amount of an amine, preferably a substituted hindered amine, in combination with phenothiazine o r other related heterocyclic moiety is added to said polymerizable monomer or oligomer. The ethylenically unsaturated monomer or oligomer encompass vinyl monomers or oligomers bearing at least one polymerizable moiety. The combination of substituted hindered amine plus phenothiazine inhibits premature polymerization in the liquid and/or vapor phase.
