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

Poly(propylene glycol) bụ polima nwere ọdịdị mmiri na-enweghị agba ruo odo odo. Ọ na-agbaze na mmiri (obere molekul) na ihe ndị na-agbaze organic dịka ketones aliphatic na alcohols, mana ọ naghị agbaze na ether na ọtụtụ aliphatic hydrocarbons. A na-enweta ya site na njupụta nke propylene oxide na propylene glycol n'okpuru nrụgide dị elu ma ọ bụ n'ihu ihe na-akpali acidic.
