Kedu ihe bụ Poly (propylene glycol) CAS 25322-69-4?

Poly (propylene glycol) bụ polymer nwere ọdịdị mmiri na-acha odo odo na-enweghị agba. Ọ bụ soluble na mmiri (obere molekụla arọ) na organic solvents dị ka aliphatic ketones na alcohols, ma insoluble na ether na ọtụtụ aliphatic hydrocarbons. A na-enweta ya site na condensation nke propylene oxide na propylene glycol n'okpuru nrụgide dị elu ma ọ bụ n'ihu onye na-emepụta acidic.
