Extract

If one defines a polymeric material as a piece of matter designed for a given and usable property, this property is not related simply to the chemical formula of the polymer. The chemical and stereochemical defects occurring during synthesis, structural organization, and processing must all be characterized, understood, and controlled.

Institute C. Sadron (ICS), established in 1954 by the French National Research organization (CNRS) as the Centre de Recherches sur les Macromolécules under the inspiration and direction of Prof. Ch. Sadron, has progressively shifted from polymer synthesis and characterization toward the understanding of the structure-property relationship in the sense just described. This has involved the creation of an engineering school staffed with equipment and research teams in rheology, processing, and mechanical properties. More than 60 permanent scientists and university professors work in the Institute; about 20 theses are submitted each year. ICS now covers a broad range of competencies, from synthesis to processing through most techniques of characterization and theoretical modeling at the molecular and macroscopic levels. This opens the way to a comprehensive research effort, which is illustrated here for polymer blends.
