Science Common Sense
1774 - What are the general properties and classification of common polymers?
Imagine having a huge box of different kinds of Legos. Just like Legos, polymers are made up of many small units called monomers that connect together to form a long chain.
Properties of Polymers:
- They can be stretchy, hard, flexible, or even melt in heat.
- They can't be easily broken down into smaller units, so they're a bit like big Lego blocks.
- Some polymers can hold a lot of weight or keep things warm.
Classification of Common Polymers:
Natural Polymers: These come from nature. Examples: silk (from spiders), wool (from sheep), and wood.
Synthetic Polymers: These are made by humans. Examples: plastic (bags and bottles), nylon (clothes and backpacks), and polyester (clothes and blankets).
Thermoplastic Polymers: These can melt and be shaped again. Examples: plastic bottles and bags.
Thermosetting Polymers: These can't be melted and shaped again. Examples: some types of car parts and phone cases.
Elastomers: These are very stretchy. Examples: rubber bands and shoe soles.
So, just like how you can sort your Legos into boxes, we can sort polymers based on what they're made of and what they can do.
