The effect of temperature on the water solubility of polyvinyl alcoholNo abstract availabledoi:10.1016/0032-3950(71)90042-6Elsevier B.V.《Polymer Science U.s.s.r》
PROBLEM TO BE SOLVED: To obtain a polyvinyl alcohol polymer which can be dissolved with a small change in torque without being brought into a state of unwetted agglomerates, leaves a small amount of insolubles, and has excellent water solubility by selecting a polyvinyl alcohol(PVA) powder cont...
Hot melt extrusion is a solid dispersion technology that can disperse the API into a polymer matrix through the application of heat and mechanical energy.This study evaluated a pharmaceutical-grade polyvinyl alcohol (PVA) as the matrix polymer for HME application. Therefore, performance ...
Then, polyvinyl acetate was saponified under the action of different alkali amounts to obtain polyvinyl alcohols having different degrees of alcoholysis. Cold-soluble polyvinyl alcohol powder is made by partially cold-milling polyvinyl alcohol by cryogenic milling. It is a water-soluble, ...
Polyvinyl alcoholFelodipineMedicine(GeneralPharmacologyIn the present study, solid dispersion (SD) of felodipine was prepared to enhance its water solubility. The SD was prepared by using polyethylene glycol (PEG 6000) and polyvinyl alcohol (PVA) as a carrier with different drug polymer ratios using ...
PURPOSE:To obtain the titled fibers, capable of increasing the dissolving temperature in water, reducing the dissolving temperature in water after the treatment with an alkali, and having improved drying efficiency, by spinning a polyvinyl alcohol (PVA) having introduced carboxyl groups into a coagulat...
Polyvinyl Alcohol: White to cream-colored granules, or white to cream-colored powder. Is odorless. Freely soluble in water at room temperature. Solution may be effected more rapidly at somewhat higher temperatures. NF category: Suspending and/or viscosity-increasing agent. Sulfurated Potash: Irregu...
of these polymers.%Methods: Amorphous solid dispersions (ASDs) of etoricoxib were prepared with polyvinyl alcohol (PVA), polyvinyl pyrrolidone (PVP) and hydroxyethyl cellulose (HEC) at 70:30w/w ratio and characterized for glass transition temperature (Tg), miscibility and intermolecular interactions. ...
Polyvinyl alcohol (PVOH) and its nanofibrillated cellulose (NFC) reinforced nanocomposites were produced and foamed and its properties—such as the dynamic mechanical properties, crystallization behavior, and solubility of carbon dioxide (CO2)—were evaluated. PVOH was mixed with an NFC fib...
