prilosec ingredients list polyvinylpyrrolidone what is it

pvp is polyvinylpyrrolidone. Polyvinylpyrrolidone (PVP) is a kind of non-ionic polymer compound. PVP is made from vinyl pyrrolidone (NVP) by bulk polymerization and solution polymerization. In the process of bulk polymerization, due to the viscosity of the reaction system, the polymer is not easy to diffuse, and the polymerization heat is not easy to remove, resulting in local overheating.

따라서, 얻어지는 생성물은 분자량이 낮고, 잔류 단량체의 함량이 높으며, 대부분 노란색을 띠고 있어 실용가치가 크지 않다. 용액 중합은 일반적으로 산업계에서 PVP를 합성하는 데 사용됩니다.

PVP 중합 생산에는 두 가지 주요 경로가 있습니다. 첫 번째는 유기 용매에서 N-2-피롤리돈(NVP)의 용액 중합이고 그 다음은 증기 스트리핑입니다. 두 번째 경로는 수용성 양이온, 음이온 또는 비이온성 모노머와 NVP 모노머의 수성 중합입니다.

순수 비닐피롤리돈의 가교결합된 단독중합체입니다. 폴리비닐피롤리돈(PVP)은 와인과 기타 음료를 변색시키는 다양한 색소와 같은 다양한 물질에 결합하는 능력을 가지고 있습니다. 그리고 불용성으로 인해 여과 후 제거가 쉽습니다.

‌ polyvinylpyrrolidone has a wide range of uses and applications. It is produced by the polymerization of N-vinylpyrrolidone under certain conditions and belongs to one of the most distinctive N-vinylamide polymers. The relative molecular mass of PVP can range from thousands to more than one million, forming a series of products including homopolymers, copolymers and crosslinked polymers, which can be divided into industrial grade, pharmaceutical grade, food grade and other specifications according to different application needs.

PVP application areas
In the field of medicine: PVP is widely used in the field of medicine, including as a drug carrier, solvent, stabilizer and so on.
Daily chemicals: Used as additives in toothpaste, mouthwash and other daily chemicals to improve product performance and user experience.
New energy industry: especially in the field of ‌ lithium batteries, PVP is used as a dispersant for electrode materials and a processing aid for conductive materials to improve battery performance.
Other fields: PVP is also used in ‌ textile printing and dyeing, ‌ coating, ‌ beer and beverage, electronics, ‌ separation film and other fields.
PVP security
PVP is classified as a Group 3 carcinogen, but its safety has been widely recognized under normal conditions of use. Use should follow the relevant safe operating procedures and storage guidelines to ensure the safety of personnel and the environment.

Polyvinylpyrrolidone (PVP) is a multifunctional polymer whose unique physicochemical properties and wide application fields make it an indispensable part of the chemical industry.
