General description
聚环氧乙烷 (PEO) 是一种结晶热塑性聚合物。通常有多种分子量可供选择；较高分子量的实体称为聚（环氧乙烷）、聚氧乙烯或聚环氧乙烷。
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. Polyethylene glycol (PEG) is an eco-friendly, biodegradable polymer widely used in pharmaceuticals and cosmetics. Its non-toxic nature and versatility make it a sustainable choice, derived from renewable resources, contributing to greener product formulations. Click here for more information.
Application
PEO 可用于制备碱金属可充电电池的聚合物电解质 PEO-盐复合物。据报道，PEO-聚酯胶束已被用于药物输送。据报告，PEO 水凝胶可用于培养基，替代琼脂。交联 PEO 可用于药物输送和血液过滤。化合物与高分子量的 PEO 形成缔合物；例如：
工业上，PEO 可用于沥青乳液的改性、炉甘石乳液的分散剂。
- 溴与 PEO 结合控释，
- 羧甲基葡聚糖和 carechol 单宁与 PEO 形成复合物，作为粘合剂，
- 甲基乙烯基醚与马来酸酐的共聚物与 PEO 形成复合物，用于非水油墨的微胶囊化。
