International Journal of Biological and Chemical Sciences, 2009 This work investigates the effect of urea formaldehyde (UF) viscosity on a composite derived from copolymerization reaction between urea formaldehyde (UF) and urea proparaldehyde (UP). Some physical properties of the urea formaldehyde/urea proparaldehyde (UF/UP) copolymer obtained at different UF viscosities (3.91-207.08 mPa.s) were evaluated.
