Prize share: 1/2
Synthetic materials like plastics are common in today's world. Plastic consists of very large molecules comprised of long chains of smaller molecules. After Karl Ziegler developed a method for creating these molecular chains using catalysts - substances that hasten the chemical process without affecting the end-products - Giulio Natta developed it further. In 1955 he discovered a catalyst that formed molecular chains with their parts oriented in certain directions. This made it possible to produce rubbery and textile-like materials.
