英文摘要	The effects of non-isothermal and isothermal crystallization on the formation of alpha- and beta-phase in isotactic polypropylene (ipp) with different content of beta-nucleating agent are investigated by differential scanning calorimetry (dsc). on non-isothermal crystallization, the content of beta-phase and regularity of its crystals are depended on both cooling rate and the content of beta-nucleating agent. the faster cooling rate is, the lower of melting peak temperature (t(mp)) and crystallization peak temperature (t(cp)) of alpha- and beta-phase are. the enthalpy of fusion (a dagger h) of beta-phase increases with cooling rate in a certain range for the sample with 0.1 wt% beta-nucleating agent (g(1)) and decreases for that with 0.3 wt% beta-nucleating agent (g(3)). on isothermal crystallization, the enthalpy of fusion of beta-phase in g(1) is higher than in g(3) which is related to the efficiency of nucleation in different concentration of nucleating center in two samples.
