Chemical Mechanisms of TOT in Polymer Stabilization

Molecular Structure and Properties

TOT, with the chemical formula (C8H17)4Sn, consists of four octyl groups attached to a central tin atom. This molecular structure imparts several key properties that make TOT an excellent choice for polymer stabilization:

1、Thermal Stability: The presence of octyl groups and the tin atom allows TOT to form stable complexes with polymers, thereby enhancing their thermal stability. These complexes prevent thermal degradation by inhibiting chain scission and cross-linking reactions.

2、UV Resistance: TOT effectively absorbs ultraviolet radiation, which is a major cause of polymer degradation. By absorbing UV light, TOT prevents photochemical reactions that lead to embrittlement and discoloration of polymers.

3、Color Retention: The ability of TOT to absorb UV light also contributes to better color retention in colored polymers. This property is particularly valuable in applications where visual aesthetics are crucial.

Reaction Mechanisms

The interaction between TOT and polymers occurs through several mechanisms:

1、Coordination Complex Formation: TOT forms coordination complexes with polymer chains, which act as barriers against oxidative degradation. These complexes hinder the formation of free radicals, which are responsible for initiating chain scission and cross-linking reactions.

2、Radical Scavenging: TOT can capture free radicals generated during polymer degradation, thereby preventing further chain scission. This radical scavenging action extends the lifespan of polymers by reducing the rate of degradation.

3、Catalytic Effects: Tin atoms in TOT can catalyze certain reactions that stabilize polymers. For instance, they can facilitate the cross-linking of polymer chains, resulting in a more robust and durable material.
