It is a completely new development, despite its designation, that could misleadingly suggest that it is a derivative of the PP-90 and PP-90M folding clandestine machine guns.

这是一个完全新的发展，尽管其名称，可能误导性表明，它是聚丙烯衍生- 90和PP - 90米折秘密机枪。

In this paper, the flax yarn will be used as the continuous reinforcement and the Polypropylene multifilament will be used as thermoplastic resin matrix. The two things will be made into a pp/flax covered yarn, which are ready to be woven into a plain fabric. The flax/pp composite board is accomplished by hot-pressing molding. Some other composite boards are also made, whose flax yarn haven been pretreated.

本课题将以亚麻纱线作为连续状增强体，聚丙烯复丝作为基体；采用包覆纱的浸渍工艺，制作了pp/亚麻包覆纱后浸料；再将包覆纱制成机织平纹布作为预成型件；通过热压成型工艺制作成复合材料板材；同时还制作了对亚麻纱线进行碱处理和偶联剂处理的复合材料板材。

In small batch bulk PP/ nucleator system, The nucleator TMB-5 was used as the impact modification for different small batch bulk PP045 and PP075 in the second part of the project.

通过XRD分析表明，β成核剂TMB—5的加入使小本体PP的结晶度提高，并对β-PP有诱导生成作用，同时发现对小本体075具有较好的增韧效果，但使其强度有所下降。

The experimental results indicate that when introducing XT-β nucleator into PP, the size of spherulite of the specimen obviously reduces and there appear typical characteristic diffraction peaks of β crystal form in the wide-angle X-ray diffraction pattern....

结果表明：在PP中引入XT-β晶型成核剂后，试样的球晶尺寸明显减小，广角X射线衍射谱图出现了典型的β晶型特征衍射峰；试样的结晶速率、结晶温度明显提高，差示扫描量热法谱图出现α晶型、β晶型2个熔融峰，β晶型含量达到总结晶量的50%～80%；XT-β晶型成核剂可使体系保持较好的力学性能，PP负荷下热变形温度提高15～40℃。

This effect is probably related to the interaction between amorphous PE in PP copolymer and PE phase in mPE and EPDM. T〓 of mPE decreases with increasing the octene content, and maximum damping of the glass transition relaxation increases.

PP／SEBS共混物中SEBS的玻璃化温度随SEBS含量的增加而降低，表明共聚PP中的PE相对SEBS中丁二烯嵌段的玻璃化松弛转变影响很小。mPE中的辛烯含量越高，其低温损耗峰的强度越高，玻璃化温度越低，低温韧性越好。

Pp The Pp index is used to summarize a system's performance in meeting two-sided specification limits.

在PP指数是用来总结系统的性能满足双面规格界限。

PP-g-MAH /down powder blend films with different content of powder were obtained after down powder were pretreated by different kinds of plasticizers,and the influence of down powder content,the type of PP,and the kind of plasticizers on the mechanical properties of blend films were studied.

采用不同增塑剂对羽绒粉体处理，制备了不同羽绒含量的马来酸酐接枝聚丙烯/羽绒粉体共混膜，分析了粉体含量、PP种类及不同增塑剂对共混膜力学性能的影响。
