Colloidal formation were subjected to appraisal, polymerisation, kinetics and step wise reactions. Mechanical tests were carried upon the foams such as measurements of the hardness and tensile strength of each foam and conclusion drawn giving each foam unique physical and chemical properties.49enpolyurethanesDEENK Témalista::Kémia
