Structure of Multinetwork Elastomer: Comparison with Hydrogen Bond Cross-Linking Elastomer.

Earlier, we developed a multinetwork elastomer (MNE) by using a covalent bond, hydrogen bond, and clay plane bond. By taking advantage of the characteristics of each cross-linking, the thermoplastic elastomer shows excellent compression set resistance (indicators of how much it recovers when the rubber is compressed), good flowability, and high tensile properties. In the previous report, it was thought that the cross-linked part was hydrogen bonded to the end face of the clay.

Multinetwork Elastomer Using Covalent Bond, Hydrogen Bond, and Clay Plane Bond.

A high-performance elastomer was obtained by a multinetworking system of a covalent bond, hydrogen bond, and clay plane bond. By taking advantage of the characteristics of each cross-linking, the thermoplastic elastomer shows excellent compression set resistance, good flowability, and high tensile properties. The hydrogen bond gives flowability due to the bond cleavage under heating.
