What do you use alkenes for?
alkenes are used to make polycarbonates such as polyethene which is used in making rope, plastics, etc.
What does ethene have that polyethene does not?
double bonds
Is the formation of polyethylene from ethylene a chemical reaction?
Polyethene is created through the polymerization of ethene. Under the right conditions of temperature, pressure and catalysis, the double bond of the ethene monomer opens up and many monomers link up to form long chains. Polyethene manufacturing processes are usually categorized into "high pressure" and "low pressure" operations. The former is generally recognized as producing conventional low density polyethene (LDPE) while the latter makes high density (HDPE) polyethene. The difference between these polyethene processes is that LDPE is formed at 1000 - 3000 bar and 80 - 300 degrees C in the presence of minute quantities of oxygen, and HDPE is formed at 10 - 80 bar and 70 - 300 degrees C in the presence of an aluminium-based catalyst.
Linear thermoplastic polymer with reference to polyethene?
THERMOPLASTIC Linear
What is polyethene used to make?
plastic bags such as sandwich bags
Is polyethene biodegradable?
Poly ethane is the UPAC name of polyethylene and is known as the most common plastic. Despite the fact that polyethene can be produced from renewable sources, no organisms can decompose them making it non-biodegradable.
What do you use alkenes for?
alkenes are used to make polycarbonates such as polyethene which is used in making rope, plastics, etc.
What are the uses of polyethene?
Polyethene can be used to make carry bags. Many apparel stores pack the newly bought items in Polyethene bags for the customers to transport them easily.
Is polyethene a hydrocarbon?
No
What is the structural formula for polyethene?
Polyethene seems to be a variant spelling of polyethylene, or polythene. I have include the Wikipedia link.
Who invented polythene?

What is polyethene made from?
it is a polymer of ethene
What does ethene have that polyethene does not?
double bonds
Why is polyethene flexible?
Polyethene is flexible due to the two covalent bonds between its carbon atoms. These double bonds allow it to be flexible.
How is the structure of pla similar to the structure of polyethene?
Yellow
What are water bottles made out of?
