EUPOC 2003, European Polymer Conference on "Stereo specific Polymerization and Stereoregular Polymers" was held on June 8-12, 2003 in Milan, Italy. The symposium was organized to celebrate the centenary of the birth of Giulio Natta, who shared the 1963 Nobel Prize in Chemistry with Karl Ziegler. The symposium provided a forum to discuss:

• New results and perspectives on novel catalysts
• Synthesis, structure, characterization, and applications of polyolefins.

The symposium covered the following topics:

• Traditional catalysts
• Metallocene catalysts
• More recent catalysts
• Molecular modeling
• Polymerization mechanisms
• Structural aspects and properties of stereoregular polymers
• New products and processes.

This volume of Macromolecular Symposia is a collection of some of the lectures presented at the symposium and the opening lecture profiling Giulio Natta as a scientist and as a man.
