Introduction

Cross-linked polyvinylpyrrolidone (PVPP) is a cross-linked polymer insoluble in water, strong acid, strong alkali and general organic solvents, which is polymerized from vinylpyrrolidone monomer under specific conditions. As an important polymer fine chemical product, PVPP has many excellent and unique properties and has been widely used in cosmetics, food, medicine and other fields.

●  Used in beverage and pharmaceutical industries

●  Due to the high molecular weight and cross-linked structure of cross-linked polyvinylpyrrolidone, it is insoluble in water but can quickly cause its network structure to expand and cause disintegration when exposed to water. In medicine, cross-linked polyvinylpyrrolidone is widely used as a disintegrant for tablets. , is also widely used as a suspension stabilizer, a complexing agent for pharmaceutical ingredients, and a complexing agent for tannins and polyphenols in botanical drugs.

●  Cross-linked polyvinylpyrrolidone (PVP-P) can form complexes with phenols and alkaloids to remove them from plant samples, thus preventing protein modification and interference, allowing for more accurate determination of protein content. . It has also been reported that cross-linked polyvinylpyrrolidone (PVP-P) can improve enzyme activity.

●  Structurally, cross-linked polyvinylpyrrolidone (PVPP) can be regarded as a cross-linked polymer in which polyvinylpyrrolidone (PVP) molecular chains with a linear molecular structure are cross-linked with each other through physical or chemical methods. Commonly used cross-linking methods include: N-vinylpyrrolidone (NVP) cross-linking method, NVP self-cross-linking polymerization method (corn flower polymerization) and compounds with multiple unsaturated groups (such as bifunctional cross-linking agents) cross-linking with NVP Joint copolymerization method. Commonly used cross-linking agents in polymerization mainly include alkylene bisacrylamide (such as N, N-methylene bisacrylamide, etc.), divinyl aromatic compounds (such as divinylbenzene, divinylethylbenzene, etc.) .
