NOVELTY - A crosslinkable fluoropolymer (polymer (FC)) comprises recurring units derived from vinylidene fluoride (VDF); and recurring units derived from a functional hydrogenated monomer (monomer (H'F)) comprising a pendant side chain.    USE - The crosslinkable fluoropolymer (polymer (FC)) is used in a crosslinkable fluoropolymer film (film (FC)). The crosslinkable fluoropolymer film (film (FC)) is used in manufacturing a crosslinked fluoropolymer film (film (FCC)). The crosslinked fluoropolymer film (film (FCC)) is used in a solar cell module. The crosslinked fluoropolymer film (film (FCC)) is used as polymer electrolyte in an electrochemical device (all claimed).    ADVANTAGE - The crosslinked fluoropolymers exhibit both enhanced chemical resistance and enhanced mechanical properties.    DETAILED DESCRIPTION - A crosslinkable fluoropolymer (polymer (FC)) comprises recurring units derived from vinylidene fluoride (VDF); and 0.01-10% by moles, with respect to the total moles of recurring units of the polymer (FC), of recurring units derived from a functional hydrogenated monomer (monomer (H'F)) comprising a pendant side chain comprising an end group (E) of any of formula (III-A) to (V-A): O-C(O)-C(R3)=CR1R2 (III-A); O-C(O)-N H-C(O)-C(R3)=CR1 R2 (IV-A); and O-C(O)-Z-C(R3)=CR1R2 (V-A), where each of R1, R2 and R3, equal to or different from each other, is independently a hydrogen atom or a C1-C3 hydrocarbon group, and Z is a bonding group of any of formula (j) and (jj): NH-X-O-C(O) (j) and NH-X-NHC(O)O-X'-O-C(O) (jj), where X and X', equal to or different from each other, are independently hydrocarbon groups selected from C1-C20 aliphatic groups, C5-C40 cycloaliphatic groups and C6-C50 aromatic, alkylaromatic or heteroaromatic groups. INDEPENDENT CLAIMS are:    (1) a process for manufacturing the crosslinkable fluoropolymer (polymer (FC)) defined above by reacting (a) a fluoropolymer (polymer (F)) comprising recurring units derived from VDF, and 0.01-10% by moles, with respect to the total moles of recurring units of the polymer (F), of recurring units derived from a functional hydrogenated monomer (monomer (HF)) comprising an end group of any of formula (I) and (II): C(O)-O-R (I) and -O-R (II), where R is a hydrogen atom or a C1-C5 hydrocarbon group comprising a hydroxyl group, and (B) a (meth)acrylic compound (compound (MA)) of any of formula (III) to (V): R1R2C=C(R3)-C(O)-O-T (III); R1 R2C=C(R3)-C(O)-NH-C(O)-O-T; and (IV) R1 R2C=C(R3)-Z-C(O)-O-T (V), where each of R1, R2 and R3, equal to or different from each other, is independently a hydrogen atom or a C1-C3 hydrocarbon group, T is a C1-C10 hydrocarbon end group comprising a functional group, and Z is a bonding group of any of formula (j) and (jj):NH-X-O-C(O) (j) and NH-X-NHC(O)O-X'-O-C(O) (jj), where X and X', equal to or different from each other, are independently hydrocarbon groups selected from C1-C20 aliphatic groups, C5-C40 cycloaliphatic groups and 06-050 aromatic, alkylaromatic or heteroaromatic groups;    (2) a crosslinkable fluoropolymer film (film (FC)) comprising a crosslinkable fluoropolymer (polymer (FC)) or the crosslinkable composition (composition (CC));    (3) a process for manufacturing a crosslinked fluoropolymer film (film (FCC)) by crosslinking, typically either by UV treatment under UV radiation or by thermal treatment, the crosslinkable fluoropolymer film (film (FC)) of (2); and    (4) a crosslinked fluoropolymer film (film (FCC)) obtainable by the process of (3), the film (FCC) comprising a crosslinked fluoropolymer (polymer (FCC)).
