Abstract:
(EN) Provided are vinylidene fluoride particles which enable the provision of an adhesive layer that rarely blocks pores formed on the surface of a separator even when the adhesive layer undergoes a thermal pressing step. Each of core-shell-type particles according to the present invention contains a core part and a shell part surrounding the periphery of the core part, wherein the core part contains a first polymer containing a structural unit derived from vinylidene fluoride in an amount of 98% by mole or more, the shell part contains a second polymer that has, as the main structural unit thereof, a structural unit derived from vinylidene fluoride and is different from the first polymer, and the second polymer has a lower melting point than that of the first polymer.
(FR) L'invention concerne des particules de fluorure de vinylidène qui permettent l'élaboration d'une couche adhésive qui bloque rarement des pores formés sur la surface d'un séparateur même lorsque la couche adhésive subit une étape de pressage thermique. Chacune des particules de type noyau-enveloppe selon la présente invention contient une partie noyau et une partie enveloppe entourant la périphérie de la partie noyau, la partie noyau contenant un premier polymère contenant un motif structurel dérivé du fluorure de vinylidène en une quantité supérieure ou égale à 98 % en moles, la partie enveloppe contenant un second polymère qui possède, en tant que motif structurel principal de celui-ci, un motif structurel dérivé du fluorure de vinylidène et est différent du premier polymère, et le second polymère présente un point de fusion inférieur à celui du premier polymère.
(JA) 熱プレスの工程を経てもセパレータの表面の孔を塞ぐことが低減された接着層を与えるフッ化ビニリデン粒子を提供する。本発明に係るコアシェル型粒子は、コア部と、当該コア部の周囲を取り囲んでいるシェル部と、を含み、当該コア部は、フッ化ビニリデンに由来する構成単位を98モル%以上含む第1の重合体を含み、当該シェル部は、フッ化ビニリデンに由来する構成単位を主構成単位とし、当該第1の重合体とは異なる第2の重合体を含み、当該第2の重合体は、当該第1の重合体よりも融点が低い。
