Used as a polymerization regulator in emulsion and suspension polymerization processes, particularly in the production of synthetic rubbers and latexes. It functions as a chain transfer agent, helping to control molecular weight and improve polymer consistency. Its structure allows for efficient incorporation into growing polymer chains, enabling precise tuning of rheological and mechanical properties in the final product. Commonly applied in adhesives, coatings, and elastomers where controlled polymer architecture is critical for performance.
