摘要： Copolymers of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP) having high HFP content and end-of-melting temperature, T.sub.m (end), as low as 200.degree. C. are disclosed. Exceptional performance as a processing aid in polyolefins results from having T.sub.m (end) of the TFE/HFP copolymer close to the processing temperature of the polyolefin. These TFE/HFP copolymers are soluble in fluorinated cyclic solvents. Copolymer/solvent systems copolymer at significant concentrations in selected solvents are fluid and stable at room temperature.
摘要翻译： 公开了具有高HFP含量和末端熔融温度Tm（末端）低至200℃的四氟乙烯（TFE）和六氟丙烯（HFP）的共聚物。 由于TFE / HFP共聚物的Tm（末端）接近聚烯烃的加工温度，所以作为聚烯烃的加工助剂具有卓越的性能。 这些TFE / HFP共聚物可溶于氟化环状溶剂。 在选择的溶剂中显着浓度的共聚物/溶剂体系共聚物在室温下是流动性和稳定性的。
