The Invention of Super Glue

In the 1940s, chemist Harry Coover discovered cyanoacrylates while researching for Eastman Kodak. Initially discarded due to their adhesive properties, these chemicals were later recognized for their potential as super glue. During the Vietnam War, super glue was used by medics to stop bleeding, and today it remains a vital tool in both medical and household settings.

What was the initial purpose of Harry Coover's research during World War II?

• To develop a new type of adhesive

• To create precision gunsights

• To improve film quality

• To find a heat-resistant polymer

Why were cyanoacrylates initially discarded during the World War II research?

• They were not transparent enough

• They adhered to everything permanently

• They were too expensive

• They were not heat-resistant

What was the focus of Coover's research after World War II?

• Developing a new type of film

• Creating heat-resistant polymers for jet canopies

• Finding a new adhesive for household use

• Improving the quality of photographic paper

What realization did Coover have about cyanoacrylates?

• They were too dangerous to handle

• They could be used as a strong adhesive

• They were not suitable for any practical use

• They could be used to improve film quality

During which conflict did super glue find a medical application?

• The Korean War

• The Vietnam War

• World War II

• World War I

What is one modern use of medical-grade super glue?

• As a household cleaner

• In surgery

• As a food preservative

• For repairing electronics
