Mineralization of radiation‐crosslinked polyvinyl alcohol/polyvinyl pyrrolidone hydrogels

Journal of Biomedical Materials Research Part A, 2007
AbstractA study of the calcification of the polyvinyl alcohol/polyvinyl pyrrolidone (PVA/PVP) hydrogels during their exposure to a calcium chloride solution or a simulated body fluid has been carried out. On the basis of the experiments, using a two‐compartment permeation cell, the diffusion of calcium ions and their subsequent deposition in the ...

Use of polyvinyl alcohol in the manufacture of polyvinyl chloride

British Polymer Journal, 1973
AbstractThe stabiliser used in the suspension polymerisation of vinylchloride influences greatly the quality of the resulting polyvinyl chloride, in particle size and distribution, and the absorption rate of plasticiser, etc.The relationship between the manufacturing conditions of polyvinylalcohol (PV‐OH) and its dispersing power was studied using ...

Polyvinyl alcohol and polyvinyl alcohol/ polyvinyl pyrrolidone biomedical foams crosslinked by gamma irradiation

Journal of Cellular Plastics, 2016
Foams for biomedical applications were made from polyvinyl alcohol, polyvinyl alcohol / polyvinyl pyrrolidone blend and their nanocomposites with nanoclay by clean processes. Air was entrapped into the aqueous polymer solutions during vigorous mixing and then the solutions were freeze-dried. The foams structure was stabilized by crosslinking via gamma

Polyvinyl Alcohol and Polyvinyl Acetate

2020
Basically only ethylene and air are needed for the production of polyvinyl acetate (PVAc) and its polymer analogous products, such as polyvinyl alcohol and polyvinyl butyrate. Polyvinyl acetate serves as the precursor for polyvinyl alcohol and, directly or indirectly, the polyvinyl acetals.

Syndiotactic polyvinyl formate and derived polyvinyl alcohol

Journal of Polymer Science Part A: General Papers, 1963
AbstractA study was made of the effect of polymerization temperature on the syndiotacticity of polyvinyl formate. Vinyl formate was polymerized with ultraviolet light initiation in the temperature range from −20 to +30°C. The value of (Ep — Et)/2 obtained, 4.5 kcal./mole, is characteristic of those values obtained by other workers for the free radical ...

Relaxation transitions in polyvinyl alcohol and porous polyvinyl formals

Inorganic Materials: Applied Research, 2017
Relaxation phenomena in polyvinyl alcohol and polyvinyl formal are studied. The internal friction spectra acquired in a free-damped torsional vibrations mode and temperature range from–150 to 120°C of two test samples each contained two distinct loss peaks, designated as α and γ, and weakly expressed β peaks.

Char formation in polyvinyl polymers I. Polyvinyl acetate

Polymer Degradation and Stability, 2002
The study of thermal and thermal-oxidative degradation of polyvinyl acetate is reported. Solid residues of degradation were analysed by FTIR microscopy in the reflection-transmission mode. Aromatization and carbonisation of the solid residues are discussed.
