Outline of Final Research Achievements

A weak gel just beyond the sol-gel transition point shows autonomic healing behavior by marked molecular motion of dangling chains. We applied this concept to crystalline polymer with low degree of crystallinity and tri-block thermoplastic elastomer with a small amount of hard segment. It is found that they show good healing behavior especially immediately after cutting. This is owing to the marked molecular motion on the surface after cutting.
