Kini Poly (propylene glycol) CAS 25322-69-4?

Poly (propylene glycol) jẹ polima pẹlu awọ ti ko ni awọ si irisi omi alawọ ofeefee. O jẹ tiotuka ninu omi (iwuwo molikula kekere) ati awọn olomi Organic gẹgẹbi awọn ketones aliphatic ati awọn ọti, ṣugbọn insoluble ninu ether ati ọpọlọpọ awọn hydrocarbons aliphatic. O ti wa ni gba nipasẹ condensation ti propylene oxide ati propylene glycol labẹ titẹ giga tabi ni iwaju ayase ekikan.
