PGRT: Natural vs Synthetic Polymers

What is a natural polymer?

• Natural polymers are small molecules that do not occur in nature.

• Natural polymers are exclusively made from minerals and metals.

• Natural polymers are large molecules made from repeating units found in nature, such as proteins and carbohydrates.

• Natural polymers are synthetic materials created in laboratories.

Give an example of a synthetic polymer.

• Jute

• Polyethylene

• Polystyrene

• Starch

Which of the following is a characteristic of synthetic polymers?

• They are naturally occurring materials.

• They are man-made materials with tailored properties.

• They have unpredictable properties.

• They are exclusively used in textiles.

Identify a property that is common in natural polymers.

• High molecular weight

• Uniform molecular structure

• Low thermal stability

• Low solubility in water

What is the primary source of natural polymers?

• Synthetic materials

• Minerals and rocks

• Water and air

• Living organisms (plants and animals)

Name a common use for synthetic polymers.

• Natural rubber

• Plastic containers

• Clothing materials

• Construction bricks

Which type of polymer is typically more durable, natural or synthetic?

• Both types of polymers have the same durability.

• Synthetic polymers are typically more durable.

• Synthetic polymers are less durable than natural ones.

• Natural polymers are always more durable.
