Preparation:

Process 1: Configure NVP into a solution with a mass fraction of 50%, use a small amount of hydrogen peroxide as a catalyst, and initiate polymerization at 50°C under the action of azobisisobutyronitrile, so that almost all NVP is converted into PVP. Then add ammonia water to the polymer to decompose the remaining azobisisobutyronitrile, the monomer polymerization conversion rate is nearly 100%, and the solid content is 50%.

Process 2: Add 0.4g dispersant P (NVP-co-VAc) and 80g dispersing medium ethyl acetate into a 250 mL four-necked flask. After stirring and dissolving in a 70℃ constant temperature water bath, add 20g monomer NVP and 0.15g initiator AIBN , React for 6h under a nitrogen atmosphere, cool and filter, place the insoluble matter in a vacuum drying box and vacuum dry for 24h to obtain a white PVP solid powder.

Most of the Polyvinylpyrrolidone polymerization uses AIBN as the initiator. There is no literature on the use of water-soluble azo initiators to initiate the synthesis of PVP, but some people are doing this. Since both NVP monomer and PVP are soluble in water, water-soluble azo initiators can be used to initiate polymerization to form linear PVP polymers. Moreover, AIBN contains cyano groups that are harmful to humans, while water-soluble azo Most of the initiators do not contain cyano groups, and PVP is mostly used in products that are in direct contact with the human body, so water-soluble azo initiators have more advantages than AIBN.

Our product performance is more stable and reliable, which guarantees the safety needs of our customers for our Shark Oilfield Viscosifiers and Suspension Agent--Liquid Xanthan Gum. Quality is our life, users are our God, pay close attention to product quality, strive to improve technical level, modern management is our endless pursuit. We have formed a series of quality consciousness and quality concept in the long-term production and management.
