More Information
Summary:This invention provides a method for shortstopping free radical polymerization reactions using a shortstopping agent comprising at least two alkyl hydroxylamines (AHAs) selected from the group consisting of primary AHAs, a mixture of at least one of each of primary and secondary AHAs, and salts thereof. A method for producing elastomers using the aforesaid shortstopping agents is also provided.
