<p><P>PROBLEM TO BE SOLVED: To obtain a TPX resin composition from which a high-quality (high thickness precision, excellent surface properties/appearance, or the like) stretched molding is produced even under general molding and processing conditions while keeping excellent heat resistance, transparency, mold release characteristics, or the like, inherent in the TPX resin. <P>SOLUTION: The TPX resin composition comprises a 4-methyl-1-pentene-based polymer (TPX) resin having 0.1-10 [g/10 minutes] MFR as a component (A) and a TPX resin having 10-500 [g/10 minutes] MFR as a component (B) and has relations between MFRA and MFRB when the MFR of the component (A) is MFRA and the MFR of the component (B) is MFRB, simultaneously satisfying numerical expression (1) to numerical expression (4) of 0.1≤MFRA≤10 (1), 10≤MFRB≤500 (2), MFRA<MFRB (3) and 4≤MFRB/MFRA (4) (MFR is a melt flow rate measured in the manner described in ASTM D1238 under 5.0 kg load at 260°C. <P>COPYRIGHT: (C)2004,JPO</p> |
