A robust and straightforward synthesis of surfactant-free poly(vinylidene fluoride) (PVDF) latexes is presented using RAFT/MADIX-mediated emulsion polymerization. VDF emulsion polymerizations were conducted in the presence of commercial poly(ethylene glycol) chains (PEG-OH) and in the presence of the same chains carrying a dithiocarbonate (xanthate) chain end (PEG-X). The identification of the stabilization mode in both cases is carefully examined, considering the irreversible chain transfer reactions well known in VDF free radical polymerization. The particle size is significantly smaller when PEG-X was used, demonstrating the positive effect on particle stabilization of the involvement of xanthate chain end in the free radical process.

由 RAFT/MADIX 反应性聚（乙二醇）聚合物链介导的偏二氟乙烯的无表面活性剂乳液聚合

使用 RAFT/MADIX 介导的乳液聚合，提出了一种稳健而直接的无表面活性剂聚（偏二氟乙烯）（PVDF）胶乳的合成方法。VDF 乳液聚合在商业聚 (乙二醇) 链 (PEG-OH) 和携带二硫代碳酸酯 (黄原酸酯) 链端 (PEG-X) 的相同链的存在下进行。考虑到 VDF 自由基聚合中众所周知的不可逆链转移反应，仔细检查了两种情况下稳定模式的识别。当使用 PEG-X 时，粒径明显更小，表明黄药链末端参与自由基过程对颗粒稳定化有积极影响。
