Polymers
Fuller did basic research on polymers at Bell Labs. He studied how the bonds of the mers determined elasticity and tensile strength. Extending the work of Carothers at Du Pont, he investigated the condensation polymers polyester and polyamide.
Bell was seeking an ideal insulator to use in coaxial cables which would be effective for high frequency operation. Realizing that polyethelene was free of polar groups, Fuller produced some of the first cable with this now common insulator.
