2: Medicine
Medical polyethylene glycol (peg) is also called polyethylene oxide (PEO). Made by ring opening polymerization of ethylene oxide linear polyether. In the field of biomedical applications are as follows
1) contact lenses with fluid
2) synthetic lubrication medicine
3) sustained release and carrier of the immobilized enzyme
4) medical polymer materials surface modification
5) to make contraceptive release. It alkoxide.
6) production of hydrophilic anticoagulant polyurethane.
7) polyethylene glycol 4000 as penetrative sugar-refining, can increase the osmotic pressure within the lumen, absorb moisture, to soften feces, volume increase, to promote intestinal peristalsis and defecation.
8) denture fixative.
9) experiment, on the study of the protein molecules can be simulated in a crowded environment, to verify the crowded environment of protein structure3: Food additive
