可以知道对甲醇羰基化这一反应，在极性溶剂中，极性较大且为非质子型的溶济能显著提高反应的速率；非极性溶剂中，介电常数较小的溶剂能增加反应速率。 |
| 6. | In the packing of amphiphilic molecules , like units of the molecules interact with each other , i . e . , the polar units associate with each other ; likewise , nonpolar unites associate to form hydrocarbon layers in the lamellar packing
在层状相中双亲分子的堆积类似于分子单元间的相互作用，即极性基团与极性基团缔合形成亲水层，而非极性基团之间缔合形成疏水层。 |
| 7. | Polyalkene is a kind of nonpolar superpolymer , easy to bring static danger caused by friction in production and use ; polyalkene antistatic master batch hdc - p1 and hdc - p5 has excellent effect only low use level , can satisfy the antistatic requirement of polyalkene products
聚烯烃是一种非极性高聚物，其制品在生产和使用过程中极易因磨擦而产生静电危害，聚烯烃抗静电母料hdc - p1和hdc - p5用量小效果好，可满足应用中对聚烯烃制品的抗静电要求。 |
| 8. | The mechanism of the surface change has beenstudied by the xps , sem , contract anglemeasurements . we discuss the roles of the tree main fators playing in the fiber - resin adhesion , and their relation to plasma parameters . the three main factors ars the key mechanical effects , the chemical bonding effcts and nonpolar dispersion force
表面粘接性能改善的原因是：由表面引入的多种含氧基团引起的化学键力和界面非极性分子色散力，由表面刻蚀坑引起的界面机械铰链力。它们对界面的粘接强度的贡献随参数而改变。 |
| 9. | Nonpolar polypropylene has bad compatibility with mmt even after organic modification to mmt . so polypropylene ( pp ) grafting acrylic acid was produced by the suspension grafting method as compatilizer . as pp / mmt nanocomposites prepared from htab modified mmt as concerned , the interlayer spacing of mmt is 4 . 61nm , 4 . 2nm and 4 . 09nm respectively when the mmt content is 1 % , 2 % and 3 % . so , the abtained nanocomposites has intercalated structure
当土含量为2 ，相容剂用量为15时力学性能最好，缺口冲击强度和拉伸强度分别达到16 . 45kj m ~ 2和35 . 77mpa ，分别比纯pp增加了280和4 . 3 ，蒙脱土的加入起到了增韧和增强的双重作用。 |
