(per) fluoropolyether block copolymers |
| abstract |
The invention relates to (per)fluoropolyether block copolymers comprising: A) a fluoropolyoxyalkylene segment (chain R a ) comprising one or more units of formula (CHXCF 2 CF 2 O)— in which X is hydrogen or fluorine; B) a (per)fluoropolyoxyalkylene segment (chain Rf), that is to say a segment comprising recurring units having at least one catenary ether bond and at least one fluorocarbon moiety, said (per)fluoropolyoxyalkylene segment being different from chain R a and having a molecular weight higher than 400 g/mol. These copolymers are endowed with improves lubricant properties or with improved water and oil-repellence properties. |
