1. Thermal Stabilization
ESBO acts as a thermal stabilizer for PVC.ESBO is a thermal stabiliser for PVC. During the processing of PVC at high temperatures, the polymer is prone to dehydrochlorination, which leads to discoloration and degradation.PVC is susceptible to dehydrochlorination at high temperatures. This leads to discoloration or degradation. The epoxy groups in ESBO can react with the hydrogen chloride (HCl) released during PVC degradation.The epoxy groups of ESBO react with the hydrogen-chloride (HCl), which is released during PVC degradation. This reaction retards the further decomposition of PVC, thereby extending its processing window and improving its long - term thermal stability.This reaction slows down the further degradation of PVC and improves its thermal stability.
2. Plasticization
ESBO also functions as a plasticizer.ESBO is also a plasticizer. It reduces the intermolecular forces between PVC chains, increasing the flexibility and processability of the polymer.It reduces intermolecular forces, increasing the flexibility of the polymer and its processability. This results in PVC products with improved mechanical properties such as elongation at break and impact resistance.The PVC products have improved mechanical properties, such as elongation when breaking and impact resistance. The plasticizing effect of ESBO is attributed to its ability to penetrate between PVC chains and separate them, allowing for easier chain - segment movement.The plasticizing effects of ESBO are attributed to the ability of ESBO to penetrate between PVC chain segments and separate them.

The reaction between ESBO and PVC involves several complex mechanisms.The reaction between ESBO PVC involves multiple complex mechanisms. The epoxy groups in ESBO can react with the free radicals generated during PVC degradation.The epoxy groups of ESBO can react to the free radicals produced during PVC degradation. For example, when PVC undergoes thermal degradation, allylic chloride groups are formed, which are highly reactive.When PVC is subjected to thermal degradation, for example, allylic-chloride groups are produced, which are highly reactive. The epoxy groups of ESBO can react with these allylic chloride - related radicals, forming more stable structures.The epoxy groups in ESBO can react to form more stable structures by reacting with these allylic-related radicals. Additionally, the reaction between ESBO and HCl released from PVC degradation follows an acid - catalyzed ring - opening mechanism of the epoxy group.The reaction between ESBO, HCl and PVC degradation is also catalyzed by an acid - ring - open mechanism of the epoxy groups.
2. Rate - Determining Steps
The rate - determining step in the ESBO - PVC reaction is often related to the availability of reactive sites on the PVC chain and the diffusion of ESBO molecules within the PVC matrix.The rate-determining step in the ESBO – PVC reaction is often correlated with the availability of reactive sites along the PVC chain, and the diffusion of ESBO molecule within the PVC matrix. At the initial stages of the reaction, the diffusion of ESBO into the PVC matrix can be a limiting factor.In the early stages of the reaction the diffusion of ESBO molecules into the matrix of PVC can be a limiting element. As the reaction progresses, the consumption of reactive sites on PVC and the formation of reaction products may also affect the reaction rate.As the reaction proceeds, the consumption and formation of reaction products can also affect the rate of reaction. The temperature plays a crucial role; higher temperatures generally increase the reaction rate by providing more energy for the reaction to overcome the activation energy barrier.The temperature is a key factor. Higher temperatures increase the rate of reaction by providing more energy to the reaction. However, extremely high temperatures can also lead to side reactions, such as further degradation of PVC or decomposition of ESBO itself.Extremely high temperatures can cause side reactions such as the degradation of PVC and decomposition of ESBO.
