STRETCHED PRODUCT OF THERMOPLASTIC RESIN COMPOSITION HAVING GOOD GAS-BARRIER PROPERTIES

摘要

A stretched product of thermoplastic resin composition is provided to ensure gas-barrier property and good transparency by using a resin composition of polystyrene blended with m-xylylene-containing polyamid, having the specific half crystallization time. A stretched product(1) of thermoplastic resin composition comprises a polystyrene based resin A 10~98 weight% and a polyamide resin B 2~90 weight%. The half crystallization time measured with the polarized light intensity method of the polyamide resin B is 200 second or greater at 140 deg.C. The polyamide resin B comprises a m-xylylene-containing polyamid containing a dicarboxylic acid component and a diamine component in which 70% or more of diamine component is induced from m-xylylene diamine.
