Thermoplastic perhalogenated (co)polymers of chlorotrifluoroethylene

摘要

Chlorotrifluoroethylene (CTFE) thermoplastic perhalogenated polymers, formed by the following polymer components: (I) 10-90% by weight of a CTFE homopolymer and (II) 90-10% by weight of a CTFE copolymer modified with comonomer (a) selected from one or more perfluoroalkyl vinylethers having the formula: Rf-O-CF=CF2 wherein: Rf is a C2-C5 perfluoroalkyl group, resulting in the final polymer (I) + (II), the amount of (a) being from 0,2 to 5% by moles and the CTFE the remaining part to 100% by moles.
