Abstract
Disclosed are novel compositions containing an LCP and one or more aromatic phosphonites. Also disclosed is a novel process for preparing LCPs in the presence of one or more aromatic phosphonites. The process enables the preparation of LCPs in a more controlled manner so that the LCPs have excellent thermal/oxidative stability. The LCPs are useful where the combination of good mechanical properties, excellent thermal resistance properties, and excellent thermal stability are desired, such as in electrical/electronic applications and electrical connectors.
