    • Studied chemistry at the University of Marburg, receiving his Doctorate in 1989 in polymer chemistry while in the group of Prof. Heitz. He then spent 13 months in the group of Prof. J. Economy at the University of Illinois before moving to Hoechst in October 1990 where he is in charge of investigating high-tenacity and high-modules polyaramid fibers. This work includes both synthesis and the study of various spinning techniques.

Abstract

The properties of high-modulus fibers based on aromatic monomer units linked by ester or amide groups depends on the relative monomer concentrations. The morphologies of various copolymers are examined and the relationship between the thermo-mechanical properties of the polymers and the dynamics of the individual polymer chains, as studied using dielectric spectroscopy, discussed.
