Crystallization behavior of Polypropylene/Syndiotactic1,2-polybutadiene blends
The melting and crystallization behaviors of Polypropylene/Syndiotactic 1,2-polybutadiene (PP/s-PB) blends and neat PP were studied by using DSC,the results showed that the presence of s-PB in PP would have a strong impact on the crystallization capacity of PP.The presence of s-PB in PP could increase the crystallization temperature(Tc) of PP,and the s-PB could obviously lower supercooling temperature(Tm-Tc) of PP,but the s-PB in PP have a Slightly influence on the melting temperature(Tm) of PP.The proposed reason for those are that the crosslinking s-PB in high temperature is a nucleator for PPs crystallization and increases PPs crystalline rate.However,the s-PB lowers PPs crystallinity.At the same time,the presence of PP in blends lowers s-PBs crystallinity,but the PP in blends have a Slightly influence on the melting temperature(Tm) and crystallization temperature(Tc) of s-PB.
