| 摘 要： | 本文用X射线衍射仪、差热分析仪、动态力学扭摆仪和测定有效网链密度等方法,研究了乙丙橡胶/聚丙烯(EPDM/PP)共混体系中PP的非晶部分和EPDM的相互渗透。EPDM和PP不具有互溶性,但PP的非晶部分和EPDM两相界面处有较强的相互渗透,即部分互容性。有效链密度和性能间关系的数据表明,共混体系不一定存在硫化胶那样的对应关系。

| Abstract: | Studies were carried out on interfacial penetration of EPDM and amorphous portion of PP in EPDM/PP blends. Observations made with torsion pendulum, differential scanning calo-rimetry and wide-angle x-ray diffraction indicated that, though no compatibility between EPDM and PP, there existed interfacial penetration and thus partial interfacial compatibility between two amorphous phases. X-ray diffraction studies revealed that unit cell dimensions of PP did not change in the presence of EPDM. The influence of effective network chain density on mechanical properties of usual rubber vulcanizates did not apply in the case of vulcanized EPDM/PP blends. |
