What are in simple polymers?
Polyethylene is the simplest synthetic polymer. It’s made up of just one kind of monomer—ethylene, which is made of two carbon atoms and two hydrogen atoms. (Other polymers can be made of two or more different monomers.) Polyethylene is formed when many thousands of ethylene molecules are joined end to end.
Is a lipid a polymer?
size, they are classified as macromolecules, big (macro-) molecules made through the joining of smaller subunits. Lipids are not usually polymers and are smaller than the other three, so they are not considered macromolecules by some sources 1,2start superscript, 1, comma, 2, end superscript.
What is polymer and is it harmful?
“Polymer” is not a chemical, but rather a term for a very large covalent molecule made up of many repeating units. Human body also contains many natural polymers; starch, proteins and DNA. A vast majority of polymers are safe , and even most artificial polymers, such as polyethylene (one of the simplest) is safe .
What things are made of polymers?
There are number of commercially produced polymers available that target various applications. Electrical switches and related components, tableware, adhesives, hoses, foam mattresses, safety helmets, and vehicle parts, etc. are some of the applications made of thermosetting polymers.
What are the uses of polymers?
Uses of polymers. Polymers are used in almost every area of modern living. Grocery bags, soda and water bottles, textile fibers, phones, computers, food packaging, auto parts, and toys all contain polymers. Even more-sophisticated technology uses polymers.
What are the 4 classes of polymers?
Synthetic polymers are human-made polymers. They can be classified into four main categories: thermoplastics, thermosets, elastomers, and synthetic fibers. They are commonly found in a variety of consumer products. Various main chains and side chains are used to make different synthetic organic polymers.
