Application of Interpolymer Complexation of Polyvinyl-
Interpolymer complex formation of polyvinylpyrrolidone (PVP) with carboxyvinyl polymer (CP) was examined by turbidity measurement, a binding isotherm study and Fourier-transform infrared spectroscopy. The interpolymer complex of PVP with CP was found to be formed in the unit molecular ratio of 1: 1 under ideal conditions, though the ratio of PVP in the solid complex was lower than 1: 1 under pr...
متن کاملInterpolymer complexation between copovidone and carbopol and its effect on drug release from matrix tablets.
The interaction between copovidone and Carbopol 907 is pH dependent. When the pH of an aqueous solution fell below pH 4.5, a water-insoluble complex began to form and precipitate. This complex resulted from a hydrogen-bond-induced interaction between the carboxylic groups in Carbopol 907 and the carbonyl groups of N-vinylpyrrolidone repeat units in copovidone. Consisting of these two polymers a...
متن کاملExperimental Approaches to Investigation of the Interaction in Between Anhydride Containing Copolymer and Poly (N-vinyl- Pyrrolidone) Blends
Polymer blending has been identified as the most versatile and economical route to producing new multi-phase polymeric materials that are able to satisfy the complex demands of performance1. Functional groups, properly located on a polymer as well as its structure, are usually responsible for i ts biological activity, biocompatibility and/or biodegradability, and may impact on its therapeutic a...
متن کاملPoly(N-Vinyl-2-Pyrrolidone-co-Acrylic Acid)- Bovine Serum Albumin Complex Formation Studied by HPLC and UV/Vis Spectroscopy
In this study the formation of water-soluble and water-insoluble complexes between bovine serum albumin (BSA) and biocompatible poly(N-vinyl-2-pyrrolidone-co-acrylic acid) (P(VP-co-AA); 2:1), anionic polymer, was studied at different protein, polymer concentrations and pH values. BSAP(VP-co-AA) complexes were studied by turbidimetric, gravimetric and chromatographic methods. Stability of the pr...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
