TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The copolymerization step comprises radical copolymerization. Preferred Components: The first monomer is a fluorovinylic monomer of formula (CF2=CFW1). The second monomer is vinyl ethers, where Y1 and Y2 is an oxygen atom. The second monomer is vinyl ethers of formula (CH2=C(R4)-Y2-CH2-R1-CH2-Z1) (IIa).R4 = -Y2-CH2-R1-CH2-Z1. Preferred Definitions:    A = -CF2-CF(W1);    W1 = F, Br, Cl, CF3 or -OCuF2u+1;    u = 1-3;    Z = -N+(R5)(R6)(R7), X-;    R5, R6, R7 = alkyl or cyclic or acyclic group;    N+R5-R7 = 4-7 membered heterocyclic group with optionally a second heteroatom comprising N, O or S, preferably 4-aza-1-azonia-bicyclo(2.2.2)octanyl; and    X = OH or halo, preferably Cl or I.    EXAMPLE - An autoclave, equipped with a pressure gauge, an inlet valve, a magnetic stirrer, a safety disc, was maintained at 30 bar pressure with nitrogen. Once the nitrogen was removed, the reactor was placed under vacuum for 25 minutes and then 2-methyl-3-(4-diazabicyclo(2.2.2)octyl)prop-1-ene chloride monomer, an initiator (tert-butyl peroxypivalate) mixed with a surfactant, ammonium perfluoroctanoate (PFOA), and 50 ml of acetonitrile/water/1,1,1,3,3-pentafluorobutane forming the solvent and chlorotrifluoroethylene (CTFE ) where successively introduced. The autoclave was regulated by heating and placed on a mechanical shaker heated to 75 degrees C for 15 hours. During the copolymerization, the pressure inside the reactor increased due to the expansion of gases and then a decrease in pressure caused by the conversion of the first gaseous fluorinated monomer (CTFE) polymer material was observed. After reaction and cooling, the reactor was left in ice for 30 minutes and then degassed. After opening the reactor, the mixture was extracted two times with 200 ml of 2-butanone and the organic phase was evaporated under vacuum. The product was dissolved in chloroform and then precipitated in methanol at room temperature to remove residual solvent, monomers, oligomers and initiators. The solution was filtered and the fluorocarbon polymer material (41% yield and 53% conversion) was then placed in a vacuum oven and dried at 50 degrees C.
