However,the spherulite growth rate of PP-cats appears slower than that of pure iPP and decrease with the increase of the EPR content,which is ascribed to the difficulty in moving of propylene chains due to the higher viscosity of PP-cats melt.

此外，与纯PP 相比，PP-cats 的成核密度大幅度提高，被认为是PP-cats 具有快的结晶速率的主要原因。

The results showed that:(1) different geometrical states of polypropylene fibres had obviously effects on the plastic shrinkage cracking properties, and PP fibres by drawing wire had better effect than fibrillated film ⅡPP fibre, the latter had better effect than fibrillated film ⅠPP fibre;(2) the plastic sh...

结果表明：(1)聚丙烯纤维几何形态对抗塑性干缩开裂性能有明显影响，拉丝PP纤维效果最好，膜裂ⅡPP纤维次之，膜裂ⅠPP纤维最差；(2)聚丙烯纤维掺量对抗塑性干缩开裂性能也有较大影响。

The flame retardant PP-g-MAH/OMMT nanocomposite master batch was prepared with maleic anhydride grafted polypropylene and organophilic montmorillonite by melt intercalation. The master batch was characterized by means of XRD and TGA. Flame retardant PP with high flame retardancy and mechanical properties was prepared with PP-g-MAH/OMMT master batch and magnesium sulfate whisker.

以聚丙烯接枝马来酸酐和有机蒙脱土为原料，通过熔融插层制备了PP-g-MAH/OMMT纳米复合阻燃母料，利用X射线衍射及热失重分析对其进行了表征，并将其与碱式硫酸镁晶须复配，制备了阻燃性能及力学性能优良的阻燃PP。

However,for the catalytic pyrolysis of sterically hindered PP,the effect of mesoporous molecular sieve sructure on pyrolysis results of PP is more important than that of mesoporous molecular sieve acidity.

而对于具有较大空间位阻的PP的催化裂解反应，催化剂酸性在一定范围内对PP的裂解结果影响不明显，表明催化剂孔结构的作用更重要，较大的孔径有利于PP的催化裂解。

The viscosity of irradiated PP/SBS was lower than that of unirradiated PP/SBS, which implied that the irradiated blends could be easily processed by injection molding.

辐照一定剂量后，由于辐射交联和裂解的进行，使PP/SBS的流变性能和结构及内耗行为发生大的变化，PP与SBS两者玻璃化转变温度间距离变小，从而改善了PP/SBS的相容性。

The optimum dyeing conditions for the WP/PP fiber was as the following: the dye temperature was 95℃, the dyeing time was 45min, the concentration of carrier Dilatin POE was 0.8g/L. The color fastness to laundering, perspiration and crocking were excellent after the WP/PP fiber has been dyed with disperse dyes of Foron.

结果表明：与纯PP纤维相比，WP/PP纤维的染色性能有了很大程度的改善，上染率提高1倍以上；优化染色工艺为：染色温度95℃，染色时间45min，载体Dilatin POE的质量浓度0.8g/L； Foron类分散染料染过的WP/PP纤维具有良好皂洗牢度、汗渍牢度和摩擦牢度。

Then, PP-g-PVAc granule was saponified to PP-g-PVOH by heterogeneous saponification technique with NaOH/KOH as catalyst in alcohol dispersing medium. During our investigation, some methods to prepare PP-g-PVOH with high saponification percentage were explored.

本文又以PP-g-PVAc为原料，NaOH/KOH为催化剂，探讨并系统研究了利用非均相皂化反应制备高醇解率聚丙烯接枝聚乙烯醇的工艺，并对本文制备得到的两种接枝共聚物PP-g-PVAc和PP-g-PVOH的结构和性能进行了表征。
