Q & A

What are polymers?

Polymers are long chain organic molecules made by repeating monomer units.

What are some examples of natural polymers?

Natural polymers include rubber, proteins, carbohydrates, and DNA.

Why are synthetic polymers commonly known as plastics?

Synthetic polymers are commonly known as plastics because they are synthetically made and are used frequently in various applications in our daily lives.

What percentage of solid waste is attributed to plastic?

Nearly one quarter of all the solid waste is plastic.

What is a long-term goal for chemists regarding plastics?

A long-term goal for chemists is to develop more biodegradable plastics that would naturally break down in the environment.

What is the common use of polyethylene?

Polyethylene is used for carrier bags and sheet plastics.

What are some applications of high-density polyethylene?

High-density polyethylene is used for drain pipes, water bottles, and containers.

Why is polytetrafluoroethylene (PTFE) used in non-stick coatings?

PTFE has a non-stick property and is also used for low friction surfaces, making it ideal for non-stick coatings on frying pans and bearings.

What unique property does Kevlar have that makes it suitable for bulletproof vests?

Kevlar has a unique strength and durability that allows it to be used in the production of bulletproof vests and jackets.

How are most alkene monomers used to make polymers obtained?

Most alkene monomers used to make polymers are obtained in some part from crude oil.

What is the primary environmental concern with the disposal of polymers?

The primary environmental concern with the disposal of polymers is that they are non-biodegradable, meaning they do not break down naturally and can persist in the environment.

What are the potential environmental impacts of burning polymers?

Burning polymers can generate heat for electricity but also produces toxic gases that can damage the environment and cause pollution.
