Polymer chemistry is a sub-discipline of chemistry that focuses on the structures of chemicals, chemical synthesis, and chemical and physical properties of polymers and macromolecules. The principles and methods used within polymer chemistry are also applicable through a wide range of other chemistry sub-disciplines like organic chemistry, analytical chemistry, and physical chemistry. Many materials have polymeric structures, from fully inorganic metals and ceramics to DNA and other biological molecules. However, polymer chemistry is typically related to synthetic and organic compositions. Synthetic polymers are ubiquitous in commercial materials and products in everyday use, such as plastics, and rubbers, and are major components of composite materials. Polymer chemistry can also be included in the broader fields of polymer science or even nanotechnology, both of which can be described as encompassing polymer physics and polymer engineering.

Herman Francis Mark was an Austrian-American chemist regarded for his contributions to the development of polymer science. Mark's x-ray diffraction work on the molecular structure of fibers provided important evidence for the macromolecular theory of polymer structure. Together with Houwink he formulated an equation, now called the Mark–Houwink or Mark–Houwink–Sakurada equation, describing the dependence of the intrinsic viscosity of a polymer on its relative molecular mass. He was a long-time faculty at Polytechnic Institute of Brooklyn. In 1946, he established the Journal of Polymer Science.

Fred Basolo was an American inorganic chemist. He received his Ph.D. at the University of Illinois at Urbana-Champaign in 1943, under Prof. John C. Bailar, Jr. Basolo spent his professional career at Northwestern University. He was a prolific contributor to the fields of coordination chemistry, organometallic, and bioinorganic chemistry, publishing over 400 papers. He supervised many Ph.D. students. With colleague Ralph Pearson, he co-authored the influential monograph "Mechanisms of Inorganic Reactions", which illuminated the importance of mechanisms involving coordination compounds. This work, which integrated concepts from ligand field theory and physical organic chemistry, signaled a shift from a highly descriptive nature of coordination chemistry to a more quantitative science.

Carl Shipp "Speed" Marvel was an American chemist who specialized in polymer chemistry. He made important contributions to U.S. synthetic rubber program during World War II, and later worked at developing polybenzimidazoles, temperature-resistant polymers that are used in the aerospace industry, in fire-fighting equipment, and as a replacement for asbestos. He has been described as "one of the world's outstanding organic chemists" and received numerous awards, including the 1956 Priestley Medal and the 1986 National Medal of Science, presented by President Ronald Reagan.
