the grafting yield
The modified fiber has been characterized with scanning electron microscopy (SEM), elemental analysis and the grafting yield.
      
The grafting tests were carried out in different solvents varying the dose rate and irradiation time so that the grafting yield could be effectively controlled.
      
The modified fiber was characterized with IR, scanning electron microscopy (SEM), elemental analysis, XPS, contact angle measurement and the grafting yield.
      
In all cases, the polyethylene oxide (PEO) sequence of the dispersant was partly incorporated at the surface of the latex particles, but the grafting yield of polyethylene oxide chains was always limited and did not exceed 15%.
      
The grafting yield is much higher in homogeneous conditions.
      
The effects of irradiation dose, reaction temperature and reaction time on the grafting yield were studied.
      
The adhesive characteristics with the grafting yield were investigated using conventional acrylic bone cement based on poly(methyl methacrylate) [PMMA].
      
As reflected in the graph, a sharp increase in the grafting yield value of 2.7% was obtained and then this almost levelled off.
      
As the n-VI concentration rises, the diffusion of monomer into the PET fiber phase increases and leads to an increment in the grafting yield.
      
Figure 4 showed that the proton conductivity increases as the grafting yield increases.
      
It is obvious that the IEC increases in contrast to the EW that decreases as the grafting yield increases, respectively.
      
Thus, the hydration number for both solvents is found to be almost independent of the grafting yield.
      
The variation of the hydration number in water and methanol with the grafting yield is shown in Figure 2.
      
The change in the diameters of PET fibers with the grafting yield is shown in Table 4.
      
The solvent uptake for the sulfonated polystyrene pore-filled electrolyte PTFE membranes shows an increasing trend with the grafting yield.
