Polyvinyl alcohol (Mw 85000-124000, 99+% hydrolyzed) is a polyvinyl alcohol with a molecular weight of 85000-124000 and hydrolytic properties. Polyvinyl alcohol (Mw 85000-124000, 99+% hydrolyzed) forms hydrogels that can be used to simulate digestive organs and lesion models for the training of endoscopic ultrasound (EUS) and endoscopic ultrasound elastography (EUS-E). Polyvinyl alcohol with different degrees of hydrolysis can be used to self-crosslink to form cryogel, which can be used as biological excipients[1][2].
