| 英文摘要 | A composite of 60% of lanthanum stearate and 40%(mass fraction) of stearic acid was prepared and its influence on the crystallization characteristics of isotatic polypropylene (iPP) was investigated. The results showed that we had found a new kind of beta -crystalline form nucleating agent. The composite might induced rather high proportion of beta -modification. The relative content of beta -phase estimated by WAXD and DSC was 30% and 51. 8% in a PP containing 2. 5%(mass fraction) of the composite respectively. The isothermal crystallization at 130 degreesC and melting behavior examined by DSC revealed that, the composite accelerated the overall rate of crystallization remarkably. The half crystallization period t(1/2) decreased from 11. 8 min of pure PP to 7. 5 min of PP containing 2. 5% of the composite. However, the composite had no obvious influence on crystallization mode and the size of alpha -crystal unit cell. |
