An experimental method was designed to characterize the thermal stability of nucleating effect of nucleating agents by repeated heating cooling DSC experiments.The DSC results showed that calcium carbonate
sodium benzoate and terephthalic acid were the nucleating agents of polypropylene with high thermal stability of the nucleating effect
while the thermal stability of nucleating effect of pimelic acid
suberic acid
azelaic acid
and the two component nucleating agents suberic acid/calcium carbonate and azelaic acid/calcium carbonate were poor.But the two-component nucleator
pimelic acid/calcium carbonate exhibited good thermal stability
which infer that there are some interactions between pimelic acid and calcium carbonate.
