Studies on Blending Process, Blend Morphology and Mechanical Properties of Polymer Blends.

该研究项目旨在与美国阿克伦大学（APEC）聚合物工程中心合作开展“聚合物共混工艺、共混形态和机械性能的研究”。本项目期间，我们可邀请APEC共9名研究人员，包括本项目成员在内的15名日本研究人员访问APEC进行合作研究。本研究由上述研究者分别和/或合作负责以下四项课题。(1)混合机及混合工艺的研究。该课题由j.l. White等人在APEC进行研究。已经在APEC设计并制造了新的混合机。Kitao等人。将在日本京都工业大学（KIT）制备的材料，用双螺杆挤出机（Twin Screw extr挤出机）共混后带回KIT，并在KIT观察共混物的形貌和力学性能。(2) b…More lending的形态学测量与分析。由于T. Kyu有很好的仪器来观察共混物的形貌，本课题也在APEC进行了研究。我们的研究生H. Takahashi在T. Kyu的指导下访问学习。他将材料带到APEC并研究了它们的相分离动力学。(3)共混物力学性能的测量与分析。我们的研究生I. Nishimura访问APEC，制作橡胶共混物并带回KIT，在T. Soen等人的指导下，在KIT使用专门设计的仪器对其力学性能进行了测量和分析。(4)开发计算机程序，建立共混物、共混物形貌和共混物实用性能数据库。本课题由T. Soen等人在KIT进行研究。即利用课题(3)得到的结果，将其断裂强度、断裂伸长率、硬度、回弹率、湿滑指数等实用性能存储到数据库中，采用因子分析法进行分析。少

This Research Project intended to develope "Studies on Blending Process, Blend Morphology and Mechanical Properties of Polymer Blends" in cooperation with Polymer Engineering Center at the University of Akron (APEC), USA.In the term of this project, we could invite 9 investigators in total from APEC, and 15 Japanese investigators, including members out of this project, visited to APEC for cooperative research.This research was performed by the above investigators in charge of following four subjects separately and/or cooperatively.(1) Study on blending machine and blending process.This subject was researched at APEC as J. L. White et al. Designed and constructed new blending machine already in APEC. Kitao et al. Carried materials which prepared in Kyoto Institute of Technology (KIT), and blended them by the machine (Twin Screw Extruder) and carried back to KIT and the morphology and mechanical properties of the blends were observes at KIT.(2) Measurement and analysis of morphology of b … More lends.This subject was also researched at APEC as T. Kyu have good instruments to observe the blends morphology. Our graduate student H. Takahashi visited to study under direction of T. Kyu. He carried materials to APEC and investigated their phase separation kinetics.(3) Measurement and analysis of mechanical properties of blends.Our graduate studeny I. Nishimura visited to APEC and made rubber blends and carried back to KIT, and measured and analized their mechanical properties at KIT using a specially designed instrument under the direction of T. Soen et al.(4) Developement of computer programs to make the data-base relating blending compounds, blends morphology and practical properties of blends.This subject was researched at KIT under the direction of T. Soen et al. That is, using the results obtaited on subject (3) and their practical properties like as strength at breakage, elongation at breakage, hardness, reboundness, wet skid index etc. were stored onto the data-base and analyzed by the factor analysis method.
