COVER STORY Origin of Polymer Science and Technology : Rubbery State |
| Rubbery state, which is distinguished from three states of matter, is a specific state characteristic of polymers that reflect a nature of chain macromolecules as strands. The rubbery state has played an important role in polymer science and technology, which has held a unique place in industry. However, many fundamental scientific points remain unsolved, even though the rubbery state was studied in 20th century. For instance, nothing is able to completely replace natural rubber with synthetic rubber in order to prepare heavy duty tires such as tires for airplane, truck and bus, despite the fact that advanced precision polymerization is adapted to prepare the rubber on the basis of the theory of rubber elasticity. It is, thus, still necessary to study fundamental points of the rubbery state and to elucidate both the exact mechanism of the rubber elasticity and factors influencing it. This may lead to the establishment of new paradigms to prepare novel polymers. The present issue focuses on up-to-date science of the rubbery state in order to seek an origin of polymer science and technology. Editors: KAWAHARA, KOJIO, SAKAI, TANAKA, and TSUNODA |
