1.位相差:フィルムの位相差はAxometrics社のAxoscanで測定した。
ポリ(シクロヘキシルマレイミド‐co‐メチルメタクリレート)(株)LGMMA PMMA 830HR)、重量平均分子量12万のスチレン‐アクリロニトリル共重合体((株)LG化学、SAN 80HF、アクリロニトリル含量:24重量%)及び重量平均分子量620万の超高分子量スチレン‐アクリロニトリル共重合体(Chemtura、Blendex‐869、アクリロニトリル含量:24重量%)をそれぞれ85:15:5の重量比で、ツイン押出器を用いて250℃、200rpmの条件でコンパウンディングして樹脂組成物を製造した。
上記PMMA 830HR、SAN 80HF及び超高分子量Blendex‐869の投入重量比を79:18:3とした以外は実施例1と同じ条件で延伸フィルムを製作し、位相差値、透過率、ヘイズ及び強靭性を測定してその測定結果を表1に示した。表1に示されているように、位相差値、光学特性及び強靭性がすべて良好であった。
スチレン‐アクリロニトリル共重合体としてSAN 80HFの代わりにSAN 82TR((株)LG化学、アクリロニトリル含量:19重量%)を用いてPMMA 830HR、SAN 82TR及び超高分子量Blendex‐869の投入重量比を80:15:5とし、MD、TD方向延伸比をそれぞれ1.6倍、3.2倍とした以外は実施例1と同じ条件で延伸フィルムを製作し、位相差値、透過率、ヘイズ及び強靭性を測定してその測定結果を表1に示した。表1に示されているように、位相差値、光学特性及び強靭性がすべて良好であった。
超高分子量スチレン‐アクリロニトリル共重合体Blendex‐869を用いずにPMMA 830HRとSAN 80HFのみをそれぞれ78:22の重量比でコンパウンディングし、MD、TD方向延伸比をそれぞれ1.5倍、3.0倍とした以外は実施例1と同じ方法で製膜/延伸して二軸延伸フィルムを製作し、位相差値、透過率、ヘイズ及び強靭性を測定してその測定結果を表1に示した。表1に示されているように、上記のフィルムは、優れた光学的特性を示したが、強靭性が足りないため、TD方向への破断が容易に発生した。
PMMA 830HR、SAN 80HF及び超高分子量Blendex‐869の投入重量比を93:4:3とし、MD、TD方向延伸比をそれぞれ1.5倍、3.0倍とした以外は実施例1と同じ方法で延伸フィルムを製作し、位相差値、透過率、ヘイズ及び強靭性を測定してその測定結果を表1に示した。表1に示されているように、透明性及び強靭性には優れたが、位相差は大きく発現されなかった。
