    摘要： The present invention pertains a fluoropolymer [polymer (F)] comprising: —recurring units derived from at least one ethylenically unsaturated fluorinated monomer [monomer (FM)]; —from 5% to 60% by moles [with respect to the total moles of recurring units of polymer (F)] of recurring units derived at least one ethylenically unsaturated fluorinated monomer containing at least one —SO2F functional group [monomer (IO)]; and —from 0.01% to 10% by moles [with respect to the total moles of recurring units of polymer (F)] of recurring units derived from at least one monomer comprising an azide group [monomer (Az)], to a process for its manufacture, to a cross-linkable composition comprising the same, to a process for cross-linking the same and to articles comprising the cross-linked polymer.

    摘要： The invention relates to a method for manufacturing low-molecular-weight polytetrafluoroethylene, comprising: a) a first step of mixing high-molecular-weight polytetrafluoroethylene with at least one additive selected from the group consisting of ethers having formula R1—O—R2, wherein R1 and R2 are independently selected among C1-C10 straight or branched aliphatic group, C4-C10 alicyclic or heterocyclic groups, C5-C10 aromatic or heteroaromatic groups; (per)fluorinated vinyl ethers; (per)fluorinated olefins; and optionally substituted aromatic hydrocarbons, and b) a second step of irradiating the so obtained mixture with ionizing radiation, said second step b) being carried out substantially in the absence of oxygen.

    摘要： The present invention pertains to semi-crystalline fluoropolymer [polymer (F)] comprising: —recurring units derived from vinylidene fluoride (VDF); —from 10% to 50% by moles [with respect to the total moles of recurring units of polymer (F)] of recurring units derived from trifluoroethylene (TrFE); and —from 0.01% to 10% by moles [with respect to the total moles of recurring units of polymer (F)] of recurring units derived from at least one monomer comprising an azide group [monomer (Az)], to a process for its manufacture, to a crosslinkable composition comprising the same, to a process for crosslinking the same and to a method for manufacturing one of electrical and electronic devices using the same.
