| 4. | The waxd spectra of pcn suggested that silicate layer induced crystallization process of 8 crystal form of pp , and decreased the sizes of a crystal form , thus the mechanic properties of pcn were enhanced
广角xrd的数据显示，纳米无机片层可诱发pp -晶型的生成，并且有随蒙脱土含量增大而增加的趋势。 |
| 5. | The rheological experienments suggested that the viscosity of pcn was less than pp " s and decreased with increasing content of montmorillonite . the effects of silicate layer on rheological behaviors of pcn are important to process performance of pcn
材料的毛细管流变测试表明，复合材料加工流动性随着蒙脱土含量的增加而得以改善，其粘度要低于纯pp的粘度，这对加工成型极有指导意义。 |
| 6. | Pp / montmori 1loni te nanocompos1tes ( pcn ) were prepared in two steps . in the first step , mother materia1 was synthesi zed by in - - situ gmft - - fnterca1a tion method , and pcn was prepared by b1ending p1ai n pp and mother material on twin screw extruder in the second step
通过原位接枝插层法制备了pp蒙脱土纳米复合增强母料，然后将pp与母料在双螺杆上共混制得pp蒙脱土纳米复合材料( pcn ) 。 |

首先考察了插层剂对蒙脱土片层间距的影响，小角x -衍射表明在插层剂十六烷基三甲基溴化铵( htab )的作用下，无机土片层间距最大可被撑至4 . 0nm ，并且d _ ( 001 )值与插层剂的浓度大小有密切的关系。 |
