摘要： PURPOSE: A process is provided for preparing polytetrahydrofuran(PTHF), copolymers of tetrahydrofuran and 2-butin-1,4-diol, diesters of these polymers with C2-C20 monocarboxylic acids or monoesters of these polymers with C1-C10 monocarboxylic acids which has improved economic property by increasing THF polymerization catalyst activity. CONSTITUTION: A process is as follows: polymerizing tetrahydrofuran in the presence of one of the following telogens, water, 1,-4-butane diol, 2-butin-1,4-diol, polytetrahydrofuran with a molecular weight of between 200 and 700 Dalton, or of a C1-C10 monocarboxylic acid or a carboxylic acid anhydride produced from C2-C20 monocarboxylic acids or mixtures of these telogens on a heterogeneous carrier catalyst which contains a catalytically active amount of an oxygenous molybdenum and/or tungsten compound on an oxidic carrier material, and which has been calcined at temperatures of between 500°C and 1000°C after application of the precursor compounds of the oxygenous molybdenum and/or tungsten compounds to the carrier material precursors. Before it is used as a polymerization catalyst, the catalyst is activated by treatment with a reducing agent.
摘要翻译：目的：提供制备聚四氢呋喃（PTHF），四氢呋喃和2-丁二醇-1,4-二醇的共聚物，这些聚合物的二酯与C2-C20单羧酸或这些聚合物的单酯与C1-C10单羧酸的制备方法，通过增加THF聚合催化剂活性来改善经济性能。方法：方法如下：在下列季铵盐，水，1,4-丁二醇，2-丁烯-1,4-二醇，分子量为200-700的聚四氢呋喃之一的存在下聚合四氢呋喃道尔顿，或由C2-C20一元羧酸或这些开朗剂的混合物产生的C1-C10单羧酸或羧酸酐在含有催化活性量的氧化钼和/或钨化合物的非均相载体催化剂上的氧化物载体材料，并且在将钼和/或钨化合物的前体化合物施加到载体材料前体之后已经在500℃和1000℃之间的温度下煅烧。在用作聚合催化剂之前，通过用还原剂处理催化剂活化。
