Process for forming polyarylenethioether stretched blow-molded vessel |
摘要 |
A process for forming a polyarylenethioether stretched blow molded vessel, by a modified blow molding of a substantially linear polyarylenethioether having a melt viscosity of 3,000 to 20,000 poise [at 310 DEG C., shear rate=200 sec-1]. The modified blow molding involves injecting the polymer in a mold to form a bottomed parison, stretching the bottomed parison along its axis by means of a rod or mandrel, and the stretched bottomed parison is then subjected to blow molding to effect lateral stretching. The blow parison is then heat set.
