Method for shortstopping polymerization processes in the manufacture of synthetic rubbers
This invention is related to a new shortstopping combination for use in stopping free radical and redox intiated polymerization is the combination of hydroxylamine (free base) (HA) and i-propylhydroxylamine (IPAH). It is more effective as related N-alcylated-hydroxylamines with regard to mooney stab...

| description | This invention is related to a new shortstopping combination for use in stopping free radical and redox intiated polymerization is the combination of hydroxylamine (free base) (HA) and i-propylhydroxylamine (IPAH). It is more effective as related N-alcylated-hydroxylamines with regard to mooney stability. The combination is not corrosive to metals used in commercial equipment fr emulsion polymerization and prevents the rust formation and the formation of nitrosamins, coagulate and precipitate. |
