Abstract
Thermoprocessable copolymer, having a Melt Flow Index (MFI) between 0.01 and 1000, of the CTFE with an acrylic monomer having the general formula:CH2═CH—CO—O—R1   (I) wherein R1 is a hydrogenated radical from 1 to 20 C atoms, C1-C20, alkyl, linear and/or branched, or cycloalkyl radical, or R1 is H. The radical R1 can optionally contain: heteroatoms preferably Cl, O, N; one or more functional groups preferably selected from —OH, —COOH, epoxide, ester and ether; and double bonds; the amount of the comonomer of formula (I) ranges from 0.01 to 5% by moles.
