A process for producing by bulk polycondensation an aromatic polyester of the formula I,
wherein X is a hydrocarbon radical having 1 to 20 carbon atoms, -0-, -SO2-, -S-, or -CO-, m is 0 or 1 and n is 0 or 1; when p=0,q=r=aninteger of 3 to 600; when q = r = 0, p = an integer of 3 to 600; when p≠ 0, q ≠ 0 and r ≠ 0, p + q + r = to 600; p, q, r are integers and q = r, which comprises using a horizontal jacketed reactor provided with one or two agitator shafts bearing impellers fixed thereto and carrying out the bulk polycondensation in said reactor while circulating a heat-transfer medium through the jacket, agitator shaft(s), and, if necessary, impellers to heat or cool the reaction system to obtain a particulate material having a weight-average particle size of 0.5 to 20 mm.
一种通过体缩聚反应生产式 I 的芳香族聚酯的工艺、
其中X是具有1至20个碳原子的烃基、-0-、-SO2-、-S-或-CO-,m是0或1,n是0或1;当p=0时,q=r=3至600的整数;当q=r=0时,p=3至600的整数;当p≠0,q≠0,r≠0时,p+q+r=至600;p、q、r 为整数,且 q = r,其中包括使用水平夹套反应器,该反应器配有一个或两个搅拌轴,其上固定有叶轮,并在所述反应器中进行大块缩聚,同时通过夹套、搅拌轴以及必要时通过叶轮循环传热介质,以加热或冷却反应系统,从而获得重量平均粒径为 0.5 至 20 毫米。
