  • The Free-Radical Copolymerization of Difurylmethane with Maleic anhydride 

    Ddamba, W.A.A.; Ngila, J.C.; Mokoena, T.T.; Motlhagodi, K. (South African Journal of Chemistry. <http://ejour.sabinet.co.za/images/ejour/chem/chem_v55_a1.pdf>., 2002)
    The copolymerization of difurylmethane with maleic anhydride in the presence of azobisisobutyronitrile as an initiator has been investigated at 65 °C, 72 °C and 85 °C in different solvents. Reaction feeds containing 85 ...

  • Volumetric Properties of (Difurylmethane + Alkan-1-ol) Binary Mixtures at 298.15 K 

    Ddamba, W.A.A.; Mokate, O. (Journal of Solution Chemistry., 2006)
    Densities (ρ) of the binary systems of {difurylmethane+(ethanol or propan-1- ol or butan-1-ol or pentan-1-ol or hexan-1-ol)} have been measured with an Anton Paar DMA 4500 vibrating-tube densimeter over the entire ...

  • Work in Thermodynamics 

    Ahmad, J.; Ddamba, W.A.A. (Chemic Publishing Co., http://www.asianjournalofchemistry.com/, 2006)
    The expression for mechanical work obtained in the expansion of a gas commonly used in physical chemistry textbooks is critically examined. The mathematical form of the first law of thermodynamics is arrived at by a procedure ...
