聚醚酯抗静电剂的制备及性能OA

Using phthalic acid(PTA)as the raw material,the polyetherester durable antistatic agent was prepared through a synthesis route of esterification followed by polycondensation.The study found that the es-terification reaction efficiency was significantly improved under a micro-negative pressure condition.The opti-mized esterification conditions were:temperature 180℃,pressure-0.02 MPa,and time 3 h.The introduction of isophthalic acid(IPA)and increasing the average relative molecular weight of PEG could effectively improve the water solubility and antistatic property of the polyetherester copolymer.The latter could also enhance the wash resistance and fabric feel of the antistatic agent.The results showed that the antistatic agent HC-A04 with 8%IPA(total weight of diacid)and 33%PEG 1 540(total weight of PEG)had the best comprehensive per-formance and had a better application prospect.
