1. An article prepared from a fluoroelastomer, the fluoroelastomer being derived from an emulsion, the emulsion comprising a fluorinated emulsifier represented by the formula:
F—(CF2)t—[O(CF2)n]m—O—(CHF)o—(CF2)p—X wherein m=1 to 3; n=1 to 3; o=1; p=1; t=1 to 10; and further wherein X is selected from a group consisting of a carboxyl acid group and a salt of a carboxylic acid group, and wherein the fluoroelastomer is essentially free of cations other than NH4+ and H+. |
