Product Information

• Name: Polyvinylpyrrolidone - K15
• Brand: Biosynth
• Description: Polyvinylpyrrolidone-K15 is a water-soluble polymeric material that has been used to prepare propranolol hydrochloride. It can be synthesized by cationic polymerization of vinylpyrrolidone with a hydrophilic monomer, such as acrylamide, in the presence of an initiator and a catalyst. The reaction solution is then precipitated with methanol or ethanol to form polyvinylpyrrolidone-K15. Polyvinylpyrrolidone-K15 has been shown to inhibit the reactions between propranolol hydrochloride and liver cells, human serum, and water vapor. FTIR spectroscopy showed that hydrogen bonding occurred between propranolol hydrochloride and polyvinylpyrrolidone-K15. The phase transition temperature for this material was investigated using laser ablation and found to be around 50 degrees Celsius.
