Polyvinylpyrrolidone

Product name:Polyvinylpyrrolidone
CAS:9003-39-8
Molecular Formula:(C6H9NO)n
Specification:100g
Description:
Polyvinylpyrrolidone (PVP) is a water-soluble polymer made from the monomer N-vinylpyrrolidone.
The polymer PVP was used as a blood plasma expander for trauma victims after the first half of the 20th century.
It is used as a binder in many pharmaceutical tablets;it simply passes through the body when taken orally. However, autopsies have found that crospovidone does contribute to pulmonary vascular injury in substance abusers who have injected pharmaceutical tablets intended for oral consumption.The long-term effects of crospovidone within the lung are unknown. PVP added to iodine forms a complex called povidone-iodine that possesses disinfectant properties.This complex is used in various products like solutions, ointment, pessaries, liquid soaps and surgical scrubs. It is known for instance under the trade name Betadine.
It is used in pleurodesis (fusion of the pleura because of incessant pleural effusions). For this purpose, povidone iodine is equally effective and safe as talc, and may be preferred because of easy availability and low cost.
