Its reaction process is as follows：
By radical reaction, PPS heat chemistry behaviors be mainly shown as strand chain extension, hot oxygen crosslinking and it is that may be present
Other complex chemical reactions such as thioether sulfone.
PPS strand chain extending reaction processes are as follows：
PPS is warm, and oxygen cross-linking process is as follows：
It is as follows that PPS forms polysulfones process at high temperature：
PPS, due to generating huge conjugation group, causes material color to become to some extent in hot oxygen cross-linking process
Deep, when temperature is sufficiently high, sulfoneization reaction occurs for PPS, forms amber polysulfones (PSF).
For these reasons, there is the problem of discoloration in high whiteness polyphenylene sulfide product at high temperature, and colour stability is poor.
Cause color to deepen to some extent with the crosslinking of hot oxygen in thermal histories, the controllability of its color change degree also compared with
