Description

Poe (12) tert-Dodecylmercaptoethanol is a specialized polymerizable surfactant and chain transfer agent belonging to the class of polyoxyethylene alkyl mercaptans. This compound is valued for its dual functionality, combining the surface-active properties of a nonionic surfactant with the radical scavenging and molecular weight control capabilities of a mercaptan. It is primarily utilized in industrial polymerization processes where precise control over polymer architecture and particle stabilization is critical. Key industries that rely on this material include advanced polymer synthesis, emulsion technology, and specialty chemical manufacturing.

Application

• As a chain transfer agent (CTA) in free-radical polymerization of acrylics, vinyl acetate, and styrene to regulate molecular weight and reduce viscosity.
• As a reactive surfactant (surfmer) in emulsion and suspension polymerization for producing stable latex particles with improved film-forming properties.
• In the synthesis of specialty polymers and resins where controlled branching or telechelic structures are required.
• For the modification of surface properties in coatings, adhesives, and inks to enhance stability, gloss, and application performance.
• As an additive in photoresist formulations and other electronic chemicals where precise polymer characteristics are essential.
• In research and development of novel polymeric materials requiring specific end-group functionality.

Quality Control

Our Poe (12) tert-Dodecylmercaptoethanol is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency in composition, functionality, and purity, meeting the stringent requirements of polymerization applications. Certificates of Analysis (COA) documenting key parameters such as mercaptan content, oxyethylene unit distribution, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation and moisture absorption.
