Abstract：In view of the problems of poor water resistance, high temperature resistance and weak yellowing resistance of polyester materials, different functional silane monomers were selected to prepare a high-temperature-resistant phenyl silicone resin intermediate through hydrolytic copolymerization in this study. The influence of the ratio of organic groups to silicon atoms on its high-temperature performance was investigated. The intermediate was further used for polyester modification to obtain methyl phenyl silicone-modified polyester, and its structure was confirmed using infrared spectroscopy. The results showed that with an increase in silicone content, the hydrophobic performance of the modified polyester improved, the hardness reached 3H, adhesion improved to grade 0, and the carbon residue at 800 ℃ increases to 39%. Furthermore, the modified polyester coating showed no yellowing after being heat treated at 260 ℃ for 1 h, indicating significant application potential on cookware surfaces such as non-stick pans and air fryers.
