  Development of bio-based foam from Ximenia americana seed oil polyol: Studies on the effect of toluene diisocyanate (TDI) on some properties of the foam

  By S. I. Okoye, S. A. Osemeahon

  Abstract: Polyurethane foam is a very important and valuable industrial product. In this study, polyol synthesized from Ximenia americana seed oil was used in the production of bio-based polyurethane foam. Different amounts (2mL, 4mL, 6mL, 8mL and 10mL) of toluene diisocyanate (TDI) were used in the formulation of the foams, and the effect of the varied amount of TDI was investigated by studying the foams’ properties such as the density, tensile …

  Synthesis and Characterization of Emulsion Paint Binder from a Copolymer Composite of Dimethylol Urea/Polystyrene

  By Ayodele Akinterinwa, S. A. Osemeahon, I. I. Nkafamiya, O. N. Maitera

  Abstract: AbstractIn our desire to reduce formaldehyde emission from urea formaldehyde resin (UF), dimethylol urea (DMU) was synthesized. Liquid polystyrene (PS) obtained from waste PS material was copolymerized by blending with the DMU at varying concentrations (10–70%). Infrared spectra infers a reactive blending between DMU and PS, while some physical property tests carried out reveals reduction in moisture uptake, rigidity and further reduction in formaldehyde emission among the favorable changes in …
