ABSTRACT:
The present invention is a process for making shaped articles by injecting a thermoplastic or thermoset polymer into a mold cavity in which is maintained at atmosphere containing between 0.1 mole % and 50 mole % F.sub.2 and at least 20 ppm O.sub.2 while said polymer is being injected into the mold. The process results in shaped articles having altered physical and chemical characteristics. A weld line formed where two interfaces of the polymer are joined in the mold cavity serves as a clean break point when pressure is applied to an article formed by the process. The atmosphere in the mold cavity may contain SO.sub.3.
