    • PURPOSE: Acryl-based particles are provided to have excellent compatibility with binder and solvent, maintaining high cross-linking degree, and capable of remarkably increasing dispersity in case applied to a diffusion film. CONSTITUTION: Acryl-based particles are formed by polymerizing a (meth)acrylate-containing monomer with a crosslinking agent. The crosslinking agent comprises a first crosslinking agent comprising a first cross-linking agent which contains -OH and/or-COOH, containing three or more (meth)acryl group. The dispersion index of the acrylic particles is 20-60%. A manufacturing method of the acrylic particles comprises: a step of manufacturing a monomer mixed solution by mixing the (meth)acrylate-containing monomer with the crosslinking agent and an initiator, and a step of suspension polymerization of the monomer-mixed solution.
    • 目的:提供丙烯酸类颗粒以与粘合剂和溶剂具有优异的相容性,保持高交联度,并且在扩散膜应用的情况下能够显着增加分散性。 构成:通过使含有(甲基)丙烯酸酯的单体与交联剂聚合而形成丙烯酸类颗粒。 交联剂包含含有含有三个以上(甲基)丙烯酰基的-OH和/或-COOH的第一交联剂的第一交联剂。 丙烯酸颗粒的分散指数为20-60%。 丙烯酸类颗粒的制造方法包括:通过混合含(甲基)丙烯酸酯的单体与交联剂和引发剂来制备单体混合溶液的步骤和单体混合溶液的悬浮聚合步骤。

    • PURPOSE: A thermoplastic resin composition comprising a graft copolymer having a core-shell structure with high refractivity is provided to ensure excellent appearance property and impact property. CONSTITUTION: A thermoplastic resin composition comprises (A) 100 parts by weight of a polycarbonate resin, (B) 45-55 parts by weight of a rubber-modified aromatic vinyl-based resin, and (C) 10-20 parts by weight of a core-shell graft copolymer. The shell of the core-shell graft-copolymer comprises one or more selected from the group consisting of phenylmethacrylate, cyclohexylmethacrylate, benzylmethacrylate, and phenoxymethacrylate. The core is a rubber polymer in which C4-6 diene rubber, acrylate rubber and silicone rubber monomers are polymerized.
