Wallace Carothers

Definition

Wallace Carothers was an American chemist who is often credited with the invention of nylon, the first synthetic fiber made entirely from petrochemicals. His work laid the foundation for modern polymer science, demonstrating how to create long-chain molecules through polymerization, which has crucial implications for understanding branched, crosslinked, and network polymers.
