Graph of: (a) Storage modulus versus temperature; (b) Loss modulus versus temperature and(c) Tan d versus temperature for all adhesives after soaked in water.which causes an increase in glass transition temperature(Ward & Hardley 1993).Morphology Characterization There are distinct micro-structural differences beforeand after aging. The rougher cleavage pattern for as-crack propagation and less crack branching as a result ofwith no yielding of the adhesive and the development of plasticization had taken place.The fracture surfaces of Albipox before and after agingare shown in Figure18. In the as-received Albipox inFigure 18a, cleaves in a petal-like form and the presenceof micro-voids indicates the cavitation of rubbery particlesthat enhanced resistance to shear yielding and thereforeincrease the tensile strength of the Albipox (Ahmad et al. more packed and denser due to cross-linking.
