Polymers are chemical compounds consisting of long chains of molecules called monomers. They occur both in nature (e.g. proteins, cellulose) and are created synthetically (e.g. plastics, rubbers, synthetic fibers). Thanks to their unique properties – lightness, strength, flexibility and resistance to chemical agents – they are used in almost every area of life. From medicine and automotive to electronics and packaging – polymers shape the modern world and open the way to innovative technologies.
