Nonisothermal Crystallization and Melting Behavior

The ternary blends cooled from the melt during DSC measurements showed two exothermic peaks due to the iPP and PB crystallization, respectively. A decrease in the Tc values for both polyolefins was observed with the increasing of the HOCP fraction in the ternary blends (Table 6.14). After crystallization, the ternary blends 

Generally, the melting point of the two forms decreased with the increase in the HOCP fraction, for blends prepared with a constant content of PB (Table 6.14). The tendency of PB to crystallize in form 1 preferably than in form 11 resulted to be strongly influenced by blend composition. The melting point of PP slightly decreased with the decrease in its fraction in the blend or with the increase in the HOCP content.
