| Outline of Final Research Achievements |
Recently, as for the thermoplastic materials in Japan, polyethylene (PE) and polypropylene (PP) occupy more than half of the annual production. Particularly, PP is widely used for many application, such as automobile so on, because PP is superior in thermal properties as well as mechanical properties. When PP is jointed with each other, heat-fusion process has usually been employed and its efficiency has been tried to be improved still now. In this study, we investigated that heat-fusion properties of PP with/without polysilane (PSi) and made clear the effect on molecular motions of PP by means of rheological measurement. As a result, it was found that, as for the heat-fusion process of PP, PSi made it shorter the process time or lower the temperature, and higher the peeling energy on the same condition. Moreover, it was found that PE had strong interaction energy with PSi on the basis of MD calculation.
