PURPOSE:To prepare a highly antistatic stretched film excellent in heat resistance, solvent resistance, transparency and mechanical strength. CONSTITUTION:This film is made from a resin composition comprising 95-99.5wt.% of a styrenic polymer having a highly syndiotactic structure and 0.5-5.0wt.% of a polyhydric alcohol fatty acid ester with an HLB of 6-9 such as polyglycerol stearate with a degree of polymerization of around 6 with or without the addition of 0.025-6.5wt.% of an organic sulfonic acid metal salt such as sodium salt of a 10-20C linear alkylsulfonic acid or an alkylarylsulfonic acid. |
