In the vast world of polymer chemistry, maintaining the stability and integrity of monomers and oligomers is paramount. Unwanted polymerization can lead to significant product loss, compromised quality, and even hazardous safety incidents. This is where specialized chemical additives like Tri-(4-hydroxy-TEMPO) phosphite, commonly known as Inhibitor 705 (CAS 2122-49-8), play a critical role. As a leading manufacturer and supplier based in China, we understand the stringent demands of the chemical industry and are proud to offer this high-efficiency polymerization inhibitor.

Understanding the Challenge: Uncontrolled Polymerization

Monomers, the building blocks of polymers, are inherently reactive. During storage, transportation, or processing, various factors can initiate a chain reaction – polymerization – that is often undesirable. This can result in the formation of gels, solids, and other impurities, drastically reducing the yield and quality of the final polymer product. In severe cases, such uncontrolled reactions can be highly exothermic, posing fire or explosion risks.

Tri-(4-hydroxy-TEMPO) phosphite: A Superior Solution

Tri-(4-hydroxy-TEMPO) phosphite (CAS 2122-49-8) is a sophisticated chemical compound designed to combat these challenges. Its primary function is as a polymerization inhibitor, acting as a highly effective free radical scavenger. The unique structure, featuring TEMPO (2,2,6,6-tetramethylpiperidin-1-oxyl) radicals, allows it to efficiently neutralize the free radicals that initiate polymerization, thereby preventing further chain growth and stabilizing the monomers.
