Process for forming container of acrylonitrile polymers by biaxial-orientation blow-moulding preform.
摘要
<p>A process for forming a container of acrylonitrile polymers by biaxial-orientation blow-molding a preform. A preform of thermoplastic resin mainly comprising acrylonitrile polymers is irradiated with an electron beam or a gamma-ray. Immediately after the irradiation, the preforms is heated at 40 DEG C or higher so as to reduce unpolymerized acrylonitrile monomer in the preform to 0.1 ppm or less. Then, the preform is biaxial-orientation blow-molded to form a container.</p>
