Alkylhydroxylamine compounds and their uses for polymerising free radical polymerization

摘要

The present invention relates to a N- isopropylhydroxylamine (IPHA) or a salt thereof, and either a primary or secondary alkyl hydroxylamine, or in combination with at least two primary alkyl hydroxylamines, are polymerized stop free radical polymerization It will provide a way. A method for producing the elastomer by using the polymerization terminator are also provided. .BACKGROUND
