Fluoropolymer composition for multilayer assemblies

A multilayer assembly comprising:

• a first layer (L1) made from a composition (C1), wherein the composition (C1) comprises:
• at least one acrylic modified VDF polymer (A) comprising at least 90% moles of recurring units derived from at least one vinylidene fluoride (VDF) monomer and at least 0.05% moles and at most 10% moles of recurring units derived from at least one hydrophilic acrylic monomer (MA) selected from the group consisting of:
• hydroxyethylacrylate (HEA) of formula:
• 2-hydroxypropyl acrylate (HPA) of either of formulae:
• acrylic acid (AA) of formula:
• and mixtures thereof, and
• at least one inorganic UV blocker compound comprising ZnO, wherein the inorganic UV blocker compound is present in an amount not exceeding 5% wt, with respect to the weight of polymer (A), and wherein the average particle size of said inorganic UV blocker compound is less than 150 nm;
• and
• a second layer (L2) made from a second composition (C2), wherein composition (C2) comprises at least one polyester (P) selected from the group consisting of:
• polyglycolide, polyglycolic acid (PGA) and copolymers thereof, optionally in admixture with other polycondensable comonomer(s);
• polylactic acid (PLA) and copolymers thereof, optionally in admixture with other polycondensable comonomer(s);
• polycaprolactone (PCL) and copolymers thereof, optionally in admixture with other polycondensable comonomer(s);
• polyethyleneadipate (PEA) and other copolymers;
• polyhydroxyalkanoate (PHA), which are the result of polycondensation of hydroxy fatty acids with chain lengths from 3 to 15 carbon atoms;
• polyethylene terephthalate (PET) and copolymers thereof, optionally in admixture with other polycondensable comonomer(s);
• polybutylene terephthalate (PBT) and copolymers thereof, optionally in admixture with other polycondensable comonomer(s);
• polytrimethylene terephthalate (PTT) and copolymers thereof, optionally in admixture with other polycondensable comonomer(s);
• and
• polyethylene naphthalate (PEN) and copolymers thereof, optionally in admixture with other polycondensable comonomer(s).
