Abstract:
The effect of xylitol and sorbitol derivatives which have different substitution group positions (e.g. ortho, meta, and para position) and types of halogen substitutions (e.g. fluoro, bromo, chloro) on crystallization temperature, melting temperature and percentage of crystallinity of polypropylene (PP) were studied. Thermal properties of PP blended with these derivatives were studied by differential scanning calorimeters (DSC). These materials functioned as a nucleating agent in PP matrix. The nucleating agent was mixed with PP using two roll mill machine and then melt spinning into fiber. It was found that the crystallization temperature of 0.5 percent wt para-chloro dibenzylidene xylitol (p-Cl-DBX) is higher than the crystallization of neat PP about 10 degrees. The amount of p-Cl-DBX that was greater than 1 percent wt, did not affect the crystallization temperature of PP. The melting temperature and percentage of crystallinity of PP did not change when these additives were added. Morphologies of xylitol and sorbitol derivatives in organic solvents showed fibril morphology with diameters ranging from 50 to 140 nm. The effect of these derivatives on tensile properties of PP fibers was also studied.
