| 发明名称 | Aqueous epoxy resin dispersions | ||
| 摘要 | The invention relates to an aqueously dispersible epoxy resin E, comprising building blocks derived from an aliphatic polyether polyol A, an epoxy resin B having at least two epoxide groups per molecule, an epoxy resin B′ having at least two epoxide groups per molecule, which may be identical to B, or different from B, an epoxy-functional fatty acid ester D, and an aromatic polyol C, a process for the preparation thereof, and a method of use thereof. | ||

| 主权项 | 1. A process of making an aqueously dispersible epoxy resin E comprising building blocks derived from an aliphatic polyether polyol A, an epoxy resin B having at least two epoxide groups per molecule, an epoxy resin B′ having at least two epoxide groups per molecule, which may be identical to B, or different from B, an epoxy-functional fatty acid ester D, and an aromatic polyol C, which process comprises reacting in a first step an aliphatic polyether polyol A and an epoxy resin B having at least two epoxide groups per molecule, wherein an adduct AB is formed, the adduct AB, a further epoxy resin B′ and an aromatic polyol C are first reacted in a second step in the presence of a catalyst until at least 90% of the epoxy groups present in the reaction mixture have been consumed, and then adding the epoxy functional fatty acid ester D, and optionally further catalyst, and carrying the reaction to completion. | ||
