Process for remelting polyamides |
摘要 |
In a process for the production of a shaped article involving the remelting of a polyamide which has been subjected to a drying stage, such as that which occurs during solid phase polymerisation, the stage of conditioning the polyamide prior to remelting can be reduced or even avoided by adding a controlled amount of water to the polymer when molten or immediately prior to its remelting. |
