Abstract

Procedure for obtaining transparent, amorphous molded bodies, especially hollow bodies, according to the injection and blowing method, characterized in that a moldable polyester mass, which shows an intrinsic viscosity of at least 0.70 dl/g and a crystallization temperature of at least 150ºC, preferably 160ºC, is injected into an injection mold, adjusting the temperature of the injection mold and the blowing nozzle approximately to the freezing temperature of the polyester or up to around 50ºC, then the mold is replaced Injected by a blow mold, the preform is blown to settle against the blow mold wall cooled to at least 20ºC below the polyester freezing temperature and then the molded body is cooled to this temperature.
