In the present study, vinyltrimethoxysilane was used to modify high-ortho novolac resin (NR) to obtain a vinyl silicone-modified phenolic oligomer (Si-mod NR). Subsequently, this oligomer is polymerized with methyl methacrylate. The mid-products (NR and Si-mod NR) and synthesized silicone-modified phenolic/acrylic resin (Ac/Si-mod NR) were characterized by Fourier transform infrared spectroscopy, and thermal properties were investigated by using thermal gravimetric analysis and differential scanning calorimetry techniques. In addition, the surface coating properties, including drying, hardness, adhesion, impact resistance, gloss, acid, alkaline, water, and solvent resistance of the films prepared from these products, were comparatively investigated. The results showed that the modification reactions yield a novel resin (Ac/Si-mod NR), which can be easily used as a surface coating material with high thermal resistance, flexibility, and excellent film properties.

在本研究中，使用乙烯基三甲氧基硅烷对高邻位酚醛树脂 (NR) 进行改性，以获得乙烯基有机硅改性酚醛低聚物 (Si-mod NR)。随后，该低聚物与甲基丙烯酸甲酯聚合。利用傅里叶变换红外光谱对中间产物（NR和Si-mod NR）和合成的有机硅改性酚醛/丙烯酸树脂（Ac/Si-mod NR）进行了表征，并通过热重分析和差示扫描研究了热性能量热技术。此外，还比较了由这些产品制备的薄膜的表面涂层性能，包括干燥、硬度、附着力、抗冲击性、光泽、耐酸、耐碱、耐水和耐溶剂性。结果表明，改性反应产生了一种新型树脂（Ac/Si-mod NR），
