Claims20
A composition comprising (i) a fluoropolymer consisting of a fluoroelastomer having a first glass transition temperature and (ii) an ionic liquid, wherein a blend consisting of (i) and (ii) has a single, second glass transition temperature, which is different from the first glass transition temperature, wherein the ionic liquid consists of (a) an alkylammonium cation and (b) a bis-(trifluoromethanesulfonyl) imide anion, and wherein the composition comprises about 10 parts by mass or more of the ionic liquid per 100 parts total mass of the fluoropolymer and the ionic liquid.
A method comprising blending (i) a fluoropolymer consisting of a fluoroelastomer having a first glass transition temperature and (ii) an ionic liquid wherein the ionic liquid consists of (a) an alkylammonium cation and (b) a bis-(trifluoromethanesulfonyl) imide anion, wherein the blend consisting of (i) and (ii) has a single, second glass transition temperature, which is different from the first glass transition temperature, and wherein the amount of the ionic liquid is about 10 parts by mass per 100 parts total mass of the fluoropolymer and the ionic liquid.
