PURPOSE:To provide a styrene resin orientation hollow molded body applicable for various applications which are excellent in heat resistance, solvent resistance, chemical resistance, hot water resistance, mechanical strength, elastic modulus, dimensional stability, or transparency. CONSTITUTION:A styrene polymer which has a syndiotactic constitution and weight-average molecular weight of which is 100,000 or more is orientated at a draw ratio of two uniaxially or biaxially at a ratio of at least 1.5 times for each axis. |
