SUPRAMOLECULAR ELASTOMER NETWORKS CONTAINING GRAFTED OLIGOAMIDE HARD COMPONENTS

摘要

An oligoamide-modified elastomer includes an elastomer having oligoamide units grafted to the elastomer and forming a plurality of sheet-like structures through hydrogen bonding, the sheet-like structures interacting through non-covalent interactions to form crystalized domains within the elastomer. In a first embodiment, the present invention provides an oligoamide-modified elastomer comprising; an elastomer with a number average molecular weight no less than 80,000 g/mol and a weight-average molecular weight no less than 100,000 g/mol having oligoamide units grafted to said elastomer and forming a plurality of sheet-like structures through hydrogen bonding, the sheet-like structures interacting through non-covalent interactions to form crystalized domains within the elastomer.
