The present study is aimed to invent new technology of improving the heat resistance for PET bottle itself. Non-heat resist Poly(ethyleneterephthalate) (PET) bottle are not available for hot contents. It shrinks remarkably according to the heat of contents when the liquid contents of about 100C are filled. So, the production of heat resist PET bottle system are produced at around 100C by a technical process devised in particular. As for the PET bottle, it is not easy to suppress the heat shrinkage in higher than 75C. So that it is produced in more than glass transition point temperature 75C. We had been executed the fundamental research to find out new method of improving the heat resistance for PET bottle itself. Especially, we examined several direction for this subject. From the viewpoint of ecology, we only research at 80C that is so low and little above for glass transition temperature 75C. We mainly examined solvent-induced crystallization method for this purpose. We are also studying the end properties of the polymer molecule chain in the crystallization.
