A polymer scientist designs new materials, such as cellulose, rubber, Kevlar, and Teflon, which are then used to make products. They work in a lab setting with a team of researchers, trying different formulations to create new polymers. As a polymer scientist, your career responsibilities and duties include understanding how materials will react with one another, whether they are safe for use by humans, and any risks they might pose to the environment. To become a polymer scientist, you need a bachelor’s degree in polymer science, organic chemistry, or a related field. Many higher-level jobs require a master’s degree or doctorate and several years of experience in the field.
