MOLECULAR COMPOSITES BASED ON HIGH-PERFORMANCE POLYMERS AND AN INTERPENETRATING LIQUID CRYSTAL THERMOSET

摘要

The invention is directed to a polymeric composition comprising a first polymer (in particular HPP) and a liquid crystal thermoset (LCT) network that interpenetrates said first polymer, which LCT network comprises LCT oligomers that are at least partly polymerized, as well as to a method for preparing such. The polymeric composition of the invention does not separate into two distinct polymer phases (first polymer and LCT) over time and has improved thermo-mechanical properties. In particular, the invention may be used to improve the properties of HPP. The polymeric composition can be used as a high-resistant material, in particular having improved heat resistance.
