  公开（公告）日：2002-04-25

  A process for the purification of polyethers prepared by acid catalyzed condensation of polyhydroxy compounds includes the steps of: (a) heating the polyether with water for a time and at temperature sufficient to substantially hydrolyze esters formed during polymerization; and (b) separating the polyether from the water. The heating of the polyether and water may be conducted under reflux at a temperature of 60 to 100° C. for a period of 2 to 20 hours. The polyether recovered from step (b) may be subjected to further washing with hot water to remove residual acid.

  通过酸催化缩合聚羟基化合物制备的聚醚的纯化过程包括以下步骤：(a)将聚醚与水加热，时间和温度足以在聚合过程中形成的酯基本水解;和(b)将聚醚与水分离。聚醚和水的加热可以在60至100°C的温度下回流进行，持续时间为2至20小时。从步骤(b)中回收的聚醚可以进一步用热水洗涤以去除残留酸。

• Two-component industrial maintenance resin coating systems and compositions and coating processes using them

  公开号：EP0024915A1

  The present invention is directed to a two-component industrial maintenance coating system. The first component comprises a polyamine terminated epoxy resin which is end capped with specifically defined monoepoxides. A co-solvent is optionally employed in the first component where the end capped adduct is a solid at room temperature. The second component comprises a low molecular weight polyepoxide resin crosslinker and optionally a diluent when the epoxy crosslinker is very viscous or solid at room temperature. Before the two components are mixed together the end capped adduct is converted to its water soluble or water dispersable salt form by reaction with a volatile acid to achieve a certain degree of salting. When the two components are mixed together the epoxide resin crosslinker is microemulsified. The composition which results upon mixing the components is curable at room temperature and exhibits an excellent balance of chemical and physical properties.

  本发明涉及一种双组分工业维护涂料体系。第一组份由端封有特定单环氧化物的多胺端封环氧树脂组成。第一组份中可选择使用助溶剂，其中端封端加合物在室温下为固体。第二组份包括低分子量的聚环氧树脂交联剂，当环氧树脂交联剂在室温下非常粘稠或呈固态时，可选择使用稀释剂。在将两种成分混合在一起之前，通过与挥发性酸反应，将端封加成物转化为水溶性或水分散性盐形式，以达到一定的盐化程度。当两种成分混合在一起时，环氧树脂交联剂被微乳化。混合后的组合物可在室温下固化，并具有出色的化学和物理性能平衡。
