Question

Polymers may also be made up of :

• A. Cellulose acetate
• B. Coal
• C. Crude oil
• D. All of the above

Answer 1

The correct option is D All of the above

Polymers are made of repeat units derived from natural gas or coal or crude oil. But building block repeat units can sometimes be made from renewable materials such as polylactic acid from corn or cellulosics from cotton linters. Some plastics have always been made from renewable materials such as cellulose acetate used for screwdriver handles and gift ribbon.
