Bulletproof vests are often made of Kevlar, a special type of nylon polymer that contains polymer chains arranged into sheets by hydrogen bonding. Kevlar was invented at DuPont in 1965 by Stephanie Kwolek and Herbert Blades.

Designer Polymers is the seventh unit in the Salters Advanced Chemistry course.
