Polymer science or macromolecular science is a subfield of materials science concerned with polymers, primarily advances in Polymer Science PDF polymers such as plastics and elastomers. Polymer chemistry or macromolecular chemistry is concerned with the chemical synthesis and chemical properties of polymers. Polymer physics is concerned with the bulk properties of polymer materials and engineering applications.

Polymer characterization is concerned with the analysis of chemical structure, morphology, and the determination of physical properties in relation to compositional and structural parameters. The earliest known work with polymers was the rubber industry in pre-Columbian Mexico. The mesoamericans knew how to combine latex of the rubber tree with the juice of the morning glory plant in different proportions to get rubber with different properties for different products, such as bouncing balls, sandals, and rubber bands. The first modern example of polymer science is Henri Braconnot’s work in the 1830s.
Despite significant advances in polymer synthesis, the molecular nature of polymers was not understood until the work of Hermann Staudinger in 1922. The World War II era marked the emergence of a strong commercial polymer industry. The growth in industrial applications was mirrored by the establishment of strong academic programs and research institute. In 1946, Herman Mark established the Polymer Research Institute at Brooklyn Polytechnic, the first research facility in the United States dedicated to polymer research.
