Abstract: Perfluoroelastomers that contain high levels (i.e. about 40 mole percent or more) of perfluoro(alkyl vinyl ether) copolymerized units can form stable blends with higher levels of perfluoropolyethers than can perfluoroelastomers that contain lower levels of perfluoro(alkyl vinyl ether) units. Thus, the former blends have better low temperature properties than the latter.

Abstract translation: 含有高水平（即约40摩尔％以上）全氟（烷基乙烯基醚）共聚单元的全氟弹性体可以形成具有比含有较低水平全氟（烷基乙烯基醚）单元的全氟弹性体更高水平的全氟聚醚的稳定共混物。 因此，前者的混合物具有比后者更好的低温性能。
