STRUCTURE-PROPERTIES RELATIONSHIP IN THERMOPLASTIC POLYURETHANES CONTAINING CARBON BLACK WITH DIFFERENT SPECIFIC SURFACE AREA AND SURFACE CHEMISTRY

摘要

In general, the variation of carbon black surface area influenced the polyurethane properties. A moderate increase in rheological and thermal properties of the polyurethane was caused by increasing the surface area of the carbon black. However, the viscoelastic and mechanical properties became worse slightly.
