As a novel vinylidene fluoride polymer and its use, provided are a binder composition, an electrode mixture, an electrode, and a non-aqueous electrolyte secondary battery including the vinylidene fluoride containing the vinylidene fluoride polymer. The vinylidene fluoride polymer includes a first structural unit derived from vinylidene fluoride and a second structural unit derived from a monomer other than vinylidene fluoride. The monomer to be the second structural unit is a primary amine, a secondary amine, or a tertiary amine having at least one of a hydroxyl group and a carboxyl group, and the content of the second structural unit is from 0.05 to 20 mol % when the total of structural units derived from all the monomers constituting the vinylidene fluoride polymer is 100 mol %.

The invention relates to the use of chopped fibers in thermoplastic composite compounds, and in particular to thermoplastic fluoropolymer compounds. The fluoropolymer matrix contains thermoplastic fluoropolymers that have been grafted with a carboxylic polar functionality, such as KYNAR ADX polymer from Arkema. The chopped fibergrafted fluoropolymer composite has increased tensile and flexural strength compared to fluoropolymer compounds that contain no grafted carboxylic grafted fluoropolymer.

A core-shell particle including a core containing a perfluoropolymer and a shell containing a non-fluorine resin, the core having a periphery coated with the non-fluorine resin at a coverage of 90% or more, the perfluoropolymer being a polymer containing a polymerized unit based on a perfluoro monomer in an amount of 90 mol % or more relative to all polymerized units, and the shell having a mass of 50 or less relative to a total mass of the core and the shell of 80. Also disclosed is a method for producing the core-shell particle.
