High mw peg
PEG, PEO, and POE refer to an oligomer or polymer of ethylene oxide. The three names are chemically synonymous, but historically PEG is preferred in the biomedical field, whereas PEO is more prevalent in the field of polymer chemistry. Because different applications require different polymer chain lengths, PEG has tended to refer to oligomers and polymers with a molecular … WebHigh molecular weight CARBOWAX™ SENTRY™ PEGs are also used to coat suppositories, providing elasticity and lubricity.
