Injection molding process with reactive gas treatment |
| 摘要 |
A process for making shaped articles by injecting a thermoplastic or thermoset polymer into a mold cavity in which is maintained a reactive atmosphere containing between 0.1 mole % and 50 mole % F2 and at least 20 ppm O2 while the polymer is being injected into the mold, such that any portion of the polymer contacts the reactive atmosphere for a time not greater than 0.5 sec.
