  A process is provided for the polymerization of fluoromonomer to an dispersion of fluoropolymer particles in an aqueous medium in a polymerization reactor, by (a) providing the aqueous medium in the reactor, (b) adding the fluoromonomer to the reactor, (c) adding initiator to the aqueous medium, the combination of steps (b) and (c) being carried out essentially free of hydrocarbon-containing surfactant and resulting in the kickoff of the polymerization of the fluoromonomer, and (d) metering hydrocarbon-containing surfactant into the aqueous medium after the kickoff of polymerization, e.g. after the concentration of the fluoropolymer in the aqueous medium is at least 0.6 wt %, the metering being at a rate reducing the telogenic activity of said surfactant while maintaining surface activity.

  本发明提供了一种在聚合反应器中将含氟聚合物颗粒分散在水介质中的含氟单体聚合工艺，该工艺(a)在反应器中提供水介质，(b)向反应器中加入含氟单体，(c)向水介质中加入引发剂、步骤(b)和步骤(c)的组合基本上在不含烃类表面活性剂的情况下进行，并导致氟onomer 的聚合反应开始，以及 (d) 在聚合反应开始后，例如在氟onomer 浓度达到一定程度后，将含烃类表面活性剂计量到水介质中。g.水介质中含氟聚合物的浓度至少为 0.6 wt % 之后，计量的速度应在保持表面活性的同时降低所述表面活性剂的伸缩活性。

  Process for reducing thermally induced discoloration of fluoropolymer resin produced by polymerizing fluoromonomer in an aqueous dispersion medium to form aqueous fluoropolymer dispersion and isolating said fluoropolymer from the aqueous medium by separating fluoropolymer resin in wet form from the aqueous medium and drying to produce fluoropolymer resin in dry form. The process comprises: pretreating the aqueous fluoropolymer dispersion and/or the fluoropolymer resin in wet or dry form; and exposing the fluoropolymer resin in dry form to fluorine.
