Description
本発明に係る樹脂組成物は、上記課題を解決するために、アクリル系樹脂を主成分とし、平均粒子径が０．０１μｍ以上１μｍ以下の範囲内の有機微粒子を含む樹脂組成物であって、上記アクリル系樹脂は、ガラス転移温度が１１０℃以上２００℃以下の範囲内であり、上記有機微粒子は、コア・シェル構造を有し、コア部が架橋を有する構造であり、シェル部にシアン化ビニル系単量体の構造単位と芳香族ビニル系単量体の構造単位とを含むことを特徴としている。 In order to solve the above problems, the resin composition according to the present invention is a resin composition containing an organic fine particle having an acrylic resin as a main component and having an average particle diameter of 0.01 μm or more and 1 μm or less, The acrylic resin has a glass transition temperature in the range of 110 ° C. or higher and 200 ° C. or lower, and the organic fine particles have a core / shell structure and the core portion has a cross-linking structure . It includes a structural unit of a vinyl monomer and a structural unit of an aromatic vinyl monomer.
また、本発明に係る樹脂組成物では、上記有機微粒子は、架橋構造を有している。 In the resin composition according to the present invention, the organic fine particles have a crosslinked structure .
樹脂組成物をフィルムとした場合の位相差を小さくするため、上記有機微粒子は、シアン化ビニル系単量体の構造単位と芳香族ビニル系単量体の構造単位とを含む。上記構成によれば、上記構造単位を有する有機微粒子は、アクリル系樹脂との相溶性に優れるため、上記有機微粒子はアクリル系樹脂中でより均一に分散することができる。このため、フィルムとした場合の耐折曲げ性（可撓性）をより改善することができる。さらには、上記有機微粒子はアクリル系樹脂中での凝集が少ないため、フィルタの目詰まりなどを起こすことなく濾過を行うことができる。これにより、異物の少ない樹脂組成物を提供することができる。 In order to reduce the phase difference when the resin composition is used as a film, the organic fine particles include a vinyl cyanide monomer structural unit and an aromatic vinyl monomer structural unit . According to the said structure, since the organic fine particle which has the said structural unit is excellent in compatibility with acrylic resin, the said organic fine particle can be more uniformly disperse | distributed in acrylic resin. For this reason, the bending resistance (flexibility) at the time of setting it as a film can be improved more. Furthermore, since the organic fine particles are less aggregated in the acrylic resin, it is possible to perform filtration without causing clogging of the filter. Thereby, the resin composition with few foreign materials can be provided.
また、樹脂組成物をフィルムとした場合の可撓性を改善するため、上記有機微粒子は架橋構造を有している。 Further, in order to improve flexibility when the resin composition is used as a film, the organic fine particles have a crosslinked structure .
また、樹脂組成物中でより均一に分散させるため、上記有機微粒子はコア・シェル構造を有する。つまり、上記有機微粒子は、中心の部分（コア）のみに多官能性化合物由来の構造を有し、中心の部分を囲む部分（シェル）には、樹脂組成物を構成するアクリル系樹脂との相溶性が高く、且つフィルムとした場合における位相差を低下させる構造を有することが好ましい。これより、有機微粒子は上記樹脂組成物中でより均一に分散することができ、フィルムとした場合の耐折曲げ性（可撓性）をより改善することができる。さらには、上記有機微粒子はアクリル系樹脂中での凝集が少ないため、フィルタの目詰まりなどを起こすことなく濾過を行うことができる。これにより、異物の少ない樹脂組成物を提供することができる。 Moreover, in order to disperse | distribute more uniformly in a resin composition, the said organic fine particle has a core shell structure . That is, the organic fine particles have a structure derived from a polyfunctional compound only in the central part (core), and the part surrounding the central part (shell) is in phase with the acrylic resin constituting the resin composition. It is preferable to have a structure that has high solubility and lowers the retardation in the case of a film. Thus, the organic fine particles can be more uniformly dispersed in the resin composition, and the bending resistance (flexibility) in the case of a film can be further improved. Furthermore, since the organic fine particles are less aggregated in the acrylic resin, it is possible to perform filtration without causing clogging of the filter. Thereby, the resin composition with few foreign materials can be provided.
上記シェル部としては、樹脂組成物を構成するアクリル系樹脂との相溶性が高い構造であり、且つフィルムとした場合の位相差を低下させることができれば特には限定されない。具体的には、上記シェル部は、上述したシアン化ビニル系単量体の構造単位と芳香族ビニル系単量体の構造単位とを有する。 The shell part is not particularly limited as long as it has a structure highly compatible with the acrylic resin constituting the resin composition and can reduce the phase difference in the case of a film. Specifically, the shell portion includes the above-described vinyl cyanide monomer structural unit and aromatic vinyl monomer structural unit .
上記コア部の構造としては、上記樹脂組成物をフィルムとした場合の可撓性を改善する効果を発現する構造であれば特には限定されず、架橋を有する構造である。また、架橋を有する構造としては、架橋ゴム構造であることが好ましい。架橋ゴム構造としては、例えばアクリル系ゴム、ポリブタジエン系ゴム、オレフィン系ゴムの構造（繰り返し構造単位）が挙げられる。 The structure of the core portion, especially if the structure to exhibit the effect of improving flexibility in the case of the resin composition and the film is not limited, a structure having a cross-linked. Moreover, as a structure which has bridge | crosslinking, it is preferable that it is a crosslinked rubber structure. Examples of the crosslinked rubber structure include structures of acrylic rubber, polybutadiene rubber, and olefin rubber (repeating structural unit).
