PROCESS AND APPARATUS FOR THE CRYSTALLISATION OF POLYTRIMETHYLENE TEREPHTHALATE. |
| 摘要 |
<p>A process for reducing the self-adhesiveness of polytrimethylene terephthalate pellets comprising the steps of: contacting melt-phase-polymerised polytrimethylene terephthalate pellets (21) having an intrinsic viscosity of a least 0.4 dl/g with an aqueous liquid (29) at a temperature within the range of 65 to 100°C for a time sufficient to induce a degree of crystallinity of at least 35% in the polytrimethylene terephthalate pellets; and a crystallisation apparatus (11) for use therein.</p> |
