Polymeric gel composed of high hydrolyzed grade poly(vinyl alcohol) and surface-modified waste fly ash has been synthesized and reported for the first time. Organic chlorosilane has been used as the surface modifier for the as-received fly ash samples for strong interaction with poly(vinyl alcohol). The resultant gels are visually transparent and thermally stable as compared to the virgin poly(vinyl alcohol). These are also mechanically stronger than the base polymer and as-received fly ash/poly(vinyl alcohol) gels due to better polymer-surface-modified fly ash interaction as reflected from their viscometric results. © 2010 The Author(s).

Some Physicomechanical Investigations on Near-transparent High Hydrolyzed Grade Poly(vinyl alcohol) Gels Impregnated with Surface-modified Waste Fly Ash

Journal of Elastomers and Plastics

A silica-rich material was generated from waste fly ash and it was subsequently characterized and experimented in ESBR compounds to find its suitability to be used as a filler for rubber compounds. This material contained 97.5% silica and 2.5% alumina. Characterisation of this material, designated as Modified Fly Ash (MFA), revealed the presence of characteristic peaks of silica in an FTIR study, and the surface area was found to be 110-115 m2/g. The effect of this material as a filler for rubber compound has been studied in ESBR compounds at low, medium and high filler loadings, and the compound properties were compared with those of compounds filled with two commercially available grades of silica, namely VN2-Silica (surface area 120-125 m2/g) and VN3-Silica (165-170 m2/g), at similar loadings. MFA showed the highest cure rate index, elongation at break and lowest heat generation among the three fillers at all the levels of filler loading. The tensile strength and 300% modulus of MFA filled compounds were inferior to those of VN3-silica, but they were closer to the values obtained for VN2-silica filled compounds. These two properties of MFA and VN2-Silica were comparable at low filler loading and at medium to high loading, the properties exhibited by VN2-Silica could be matched by using higher dosage of MFA. © Smithers Information Ltd., 2014.
