Description
重合体を小型射出成形機 CS-183-MMX(カスタム・サイエンティフィック・インスツルメンツ社製)に供給し、加熱溶融させて3分間保持する。その後、10mm×20mm×2mmの金型を用いて、金型温度60℃にて射出成形し、成形体を作製した。
得られた成形体の透過スペクトルを、分光光度計 MCPD-3000(大塚電子(株)製)により測定し、黄色度を測定した。
本発明で用いる単量体(a1)は、重合性NOR-HALSに属し、下記式(1)で表される。
本発明で用いる単量体(a2)は、メチルメタクリレートを主成分とする。尚、本発明では、全体に対して50質量%以上であることを「主成分」という。
本発明の成形材料(B)は、重合体(A)をそのまま用いても良く、重合体(A)以外の材料を含有することもできる。
単量体(a1)の構造の確認には、1H-NMR JNM-EX270(日本電子(株)製、(商品名))を用いた。
得られた成形体の透過スペクトルを、分光光度計 MCPD-3000(大塚電子(株)製)により測定し、黄色度を測定した。
得られた成形体を肉眼で観察し、着色の有無を判定した。黄色度が10以下であれば着色が無いと判定した。
成形体の全光線透過率とヘイズ値を村上色彩技術研究所製ヘイズメーターHM-65W型を用いて、JIS-K7105に従い測定した。
