摘要:
A reactive and processable fluoropolymer, obtainable by mechanical shearing of a fluoropolymer A) comprising polymerized monomer units of at least one fluorinated, optionally substituted, alkene with 2 to 8 carbon atoms and optionally at least one member selected from the group consisting of a perfluorinated vinyl ether, non-fluorinated olefin and non-fluorinated vinyl ester, and 0.3 to 7% of a compound B) which possesses a double bond (I) capable of adding to polymeric radical fragments and a II-electron system which is either conjugated with double bond (I) or has readily transferrable hydrogen atoms in the allyl or benzyl position and optionally further double bonds or reactive groups and optionally further auxiliary agents (C). The fluoropolymer is especially useful in radical addition or nucleophilic or electrophilic substitution or addition, e.g. cross-linking or grafting.
