Abstract
A liquid composition comprising: at least one fluoroionomer (I) [fluoroionomer (I-1)], the fluoroionomer (I-1) having a heat of fusion comprised between 4 and 20 J/g; and at least one fluoroionomer (I) [fluoroionomer (I-2)], the fluoroionomer (I-2) being substantially amorphous, that is to say having a heat of fusion of less than 4 J/g, and wherein the water extractable fraction of the fluoroionomer (I-2) is less than 40% wt, the liquid composition comprising the fluoroionomer (I-1) and the fluoroionomer (I-2) in a weight ratio (I-1)/(I-2) of at least 2:1.
