摘要： A process for introducing pigments or nonpigment colorants or stabilizers or mixtures thereof into a polyamide or polyester melt, comprising:
a) feeding an additive in a liquid vehicle containing volatiles into a twin screw vented extruder which is extruding a polymer melt stream;
b) mixing the polymer and additive in the extruder;
c) removing the volatiles from the resulting mixture while in the extruder; and
d) extruding a resulting substantially homogeneous polymer and additive melt.摘要翻译： 将颜料或非色素着色剂或其混合物引入聚酰胺或聚酯熔体中的方法，包括：a）将含有挥发物的液体载体中的添加剂进料到挤出聚合物熔体流的双螺杆排气挤出机中; b）在挤出机中混合聚合物和添加剂; c）在挤出机中从所得混合物中除去挥发物; 和d）挤出所得的基本均匀的聚合物和添加剂熔体。
