摘要:
A method for making a polyether monomer having at least one unsaturated site per molecule and having a desired number of alkoxyl repeating units includes the steps of reacting an active hydrogen-containing monomer having at least one unsaturated site per molecule with an alkyl oxide in the presence of an alkoxylation catalyst and a polymerization inhibitor at a temperature from about 30 °C to less than 45 °C to produce a polyether monomer. In one embodiment, from about 5 to about 1000 parts by weight of a phenothiazine polymerization inhibitor per one million parts by weight of the active hydrogen-containing monomer phenothiazine compound is used as the polymerization inhibitor.
摘要(中):
制备具有每分子至少一个不饱和位点并且具有所需数目的烷氧基重复单元的聚醚单体的方法包括以下步骤:使具有至少一个不饱和部分的活性氢单体与烷基氧化物在存在下反应 的烷氧基化催化剂和阻聚剂,在约30℃至小于45℃的温度下制备聚醚单体。 在一个实施方案中,每100万重量份含活性氢的单体吩噻嗪化合物约5至约1000重量份的吩噻嗪聚合抑制剂用作阻聚剂。
