What Are Designer Polymers

The video discusses traditional and designer polymers, highlighting their properties and uses. Traditional polymers like nylon are durable but lack breathability. Designer polymers, such as Gore-Tex, offer improved features like breathability and waterproofing. The video also explores the use of designer polymers in contact lenses and tooth fillings, emphasizing their benefits over traditional materials. Designer polymers are tailored to respond to environmental changes, providing enhanced functionality in various applications.

What is a key characteristic of designer polymers compared to traditional polymers?

• They are less durable.

• They are made from natural materials.

• They are designed to respond to environmental changes.

• They are more expensive.

What is the primary benefit of using Gore-Tex in clothing?

• It is made from recycled materials.

• It allows sweat to pass through while remaining waterproof.

• It is cheaper to produce.

• It is more colorful.

How do designer polymers improve contact lenses?

• They make them more rigid.

• They allow oxygen to pass through to the eye.

• They are cheaper to produce.

• They change color in sunlight.

What is a disadvantage of traditional silver amalgam fillings?

• They are not durable.

• They are too soft.

• They contain dangerous chemicals like mercury.

• They are too expensive.

What is a photopolymer used for in tooth fillings?

• To reduce the cost of the filling.

• To make the filling more flexible.

• To harden and match the tooth's natural color when treated with light.

• To make the filling glow in the dark.
