Abstract
A polyetheresteramide compound and the method of preparing it comprise: a polyether compound containing a diamino group at the end mixed with a diacid and a diol, and being polymerized and condensed to form a polyetheresteramide compound. This polyetheresteramide is a durable anti-static resin. In addition to the anti-static property, the polyetheresteramide compound has the physical properties of the original polyester. Thus, the polyetheresteramide compound can be added into an anti-static resin and applied in general resin industry, special chemical and spinning industries. The anti-static products, such as the anti-static thin plate, anti-static bag, IC cover tape, anti-static clothes, and dustless clothes, or even broadly applied in electronic communication, semiconductor, and optoelectronic manufactures.
