Polyethylene Glycol series
Taw qhia
PEGs zoo li hloov los ntawm cov kua pob tshab rau flake nrog rau nws qhov hnyav molecular.Thiab nws yog dej solubility thiab hypotoxicity.Cov hydroxyl ntawm ob qhov kawg ntawm cov qauv molecular ntawm PEG series muaj cov yam ntxwv ntawm cawv tsawg uas tuaj yeem ua rau esterificated thiab etherificated.
