In this study, a type of silicone modified styrene-acrylate latex (SSA) was synthesized by styrene (St), vinyl trimethoxysilane (VTMS) and isooctyl acrylate (IA) through RAFT emulsion polymerization. The molecular weight and distribution (PDI) of SSA increased with VTMS contents ranging from 0 to 4%. It also enhanced the tensile strength of SSA coatings from 3.6 to 5.8 MPa. Furthermore, SSA coatings possessed the good self-healing properties. TGA and DMA indicated the thermal stability of SSA coatings increased with the increasing of VTMS contents. It also increased the water contact angle (CA) from 85 to 105° and reduced the water absorption from 3.75 to 0.8%. The open circuit potential (Eocp)-time and anodic polarization (Tafel) curves indicated the corrosion resistance enhanced with the increase of the VTMS contents. The all obtained results indicated the SSA would have great potential as weatherable and anticorrosive coatings.

在这项研究中，由苯乙烯（St），乙烯基三甲氧基硅烷（VTMS）和丙烯酸异辛酯（IA）通过RAFT乳液聚合合成了一种有机硅改性的苯乙烯-丙烯酸酯胶乳（SSA）。SSA的分子量和分布（PDI）随着VTMS含量从0％到4％的增加而增加。它还将SSA涂层的拉伸强度从3.6 MPa提高到5.8 MPa。此外，SSA涂料具有良好的自修复性能。TGA和DMA表示SSA涂层的热稳定性随VTMS含量的增加而增加。它还将水接触角（CA）从85增加到105°，并将吸水率从3.75减少到0.8％。开路电势（Eocp）-时间和阳极极化（Tafel）曲线表明，随着VTMS含量的增加，耐蚀性增强。
