Abstract

Poly(propylene) homopolymer/fly ash (50% wt) composites have been prepared from two samples of fly ash that differ in terms of the geographic source of coal feedstock, which left one of the samples with a higher group I and II metal content. A screening study indicated that Lubrizol Solplus® C800 (an unsaturated carboxylic acid dimer coupling agent), initiated with dicumyl peroxide, conferred the best strength-toughness balance to the composites. In some cases, however this was related to detachment of the interfacial region due to possible extraction of PP-C800 adduct-group I and II ion reaction products. Interfacial adhesion was arguably too high in the case of the fly ash sample bearing a lower level of group I and II ions. These deductions were also supported by DSC data. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
