用于含氟聚合反应的乳化剂及含氟聚合物的制备方法
摘要：
本发明具体涉及一种用于含氟聚合反应的乳化剂及含氟聚合物的制备方法。本发明所述该乳化剂有效成分通式为H(CF2CF2)3COOM，M为H、Li、Na、K或NH4。该乳化剂毒性小，环境友好；使用该乳化剂有效控制了含氟聚合物乳液的初级粒子粒径在0.15～0.35微米，并可以得到分子量高的聚四氟乙烯分散树脂。
摘要（英）：

The invention relates to an emulsifier for a fluorine-containing polymerization reaction and a preparation method of a fluorine-containing polymer. The emulsifier has the effective ingredient general formula of H(CF2CF2)3COOM, wherein M is H, Li, Na, K or NH4. The emulsifier is low in toxicity and is environmentally friendly; with use of the emulsifier, the particle size of primary particles of a fluorine-containing polymer emulsion can be effectively controlled at 0.15-0.35 microns, and a polytetrafluoroethylene dispersion resin with high molecular weight can be obtained.
