Between June 6-10, 1988, the Third Chemical Congress of North America was held at the Toronto Convention Center. At this rare gathering, fifteen thousand scientists attended various symposia. In one of the symposia, Professor Pierre-Gilles de Gennes of College de France was honored as the 1988 recipient of the Amer ican Chemical Society Polymer Chemistry Award, sponsored by Mobil Chemical Corporation. For Professor de Gennes, this international setting could not be more fitting. For years, he has been a friend and a lecturer to the world scientific community. Thus, for this special occasion, his friends came to recount many of his achievements or report new research findings mostly derived from his theories or stimulated by his thoughts. In this volume of Proceedings, titled New Trends in Physics and Physical Chemistry of Polymers, we are glad to present the revised papers for the Symposium and some contributed after the Symposium. In addition, we intend to include most of the lively discussions that took plaGe during the conference. This volume contains a total of thirty-six papers divided into six parts, primarily according to the nature of the subject matter: • Adsorption of Colloids and Polymers. • Adhesion, Fractal and Wetting of Polymers. • Dynamics and Characterization of Polymer Solutions. • Diffusion and Interdiffusion of Polymers. • Entanglement and Reptation of Polymer Melts and Networks. • Phase Transitions and Gel Electrophoresis.
