INTRODUCTION Polyvinyl alcohol (PVA) is a semicrystalline synthetic polymer (Figure 1), which is soluble in water, slightly soluble in ethanol and insoluble in other organic solvents (Saxena, 2004; Kadajji and Betagari, 2011; Song and Kim, 2004). Special grades of pyrogen-free povidone are available and have in the Canadian List of Acceptable Non-medicinal Ingredients. This should form an orange precipitate. Povidone is additionally used as a suspending, stabilizing, or IR has showed that flunarizine and PVP has no chemical reaction except in some cases that a best dissolution efficacy is obtained only in certain ratio between some drugs with the PVP. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.[2]. 9, 32613270 (1994), Guettari, M., Ajroudi, L., Tajouri, T., Bitar, A., Elaissari, H.: A temperature effect on the intrinsic viscosity of aqueous poly(N-vinylcaprolactam) solution. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. Polyvinyl alcohol has high flexibility and tensile strength.

It is used in pleurodesis (fusion of the pleura because of incessant pleural effusions). Except where otherwise noted, data are given for materials in their standard state (at 25 C [77 F], 100 kPa). Slightly soluble in ethanol. Its crude product comes from the polymerization of vinylpyrrolidone under basic catalyst or the existence of N, N'-divinyl amidine and further cross-inking reaction. Polyvinyl acetate water-based emulsions is often applied as a liquid that hardens to a solid when the water evaporates. Polyvinyl acetate is soluble in a number of organic solvents. PVP can also be dissolved in another molten dropping pill matrix, such as polyethylene glycol (PEG), polyoxyethylene monostearate (S-40), poloxamer and stearyl acid, glyceryl monostearate, etc for making complex matrix. It is used as a colloidal stabilizer and clarifying agent for beer clarification.
