The aim is to synthesize a novel chain extender to enhance the properties of polyurethane elastomer.
Synthesized a novel chain extender (HDF) with disulfide and imine bonds.
Incorporated HDF into polyurethane elastomer (PUE) to assess its effects.
Analyzed the mechanical and damping characteristics of the cured PUE.
PUE cured with HDF displayed outstanding damping characteristics.
Mechanical properties of the modified PUE were significantly improved.
Abstract
We synthesized a novel chain extender (HDF) featuring disulfide and imine bonds and incorporated it into PUE. The PUE cured with HDF exhibits outstanding damping and mechanical properties.
