Usually, pressure and a catalyst (initiator) are applied and the result is a polyalkene or polyolefin. Examples include polyethylene and polypropylene etc.

Where are monomers of plastics found?
They are formed from the products (i.e alkenes and alkanes) of the fractional distillation of crude oil. Alkenes and alkanes are hydrocarbons - their molecules consist of hydrogen and carbon only. Monomers of these substances bond to form long chains called polymers. Polymers are what make up plastics.
What are three types of unsaturated hydrocarbons?
Alcohol Polymer Monomer Biilogical polymers
Disadvantage of alkenes?
Alkenes are defined as any of the series of unsaturated hydrocarbons containing a double bond, including ethylene and propylene. Disadvantages include that many alkenes are insoluble in aqueous acid and side reactions are possible.
Why are fractions from crude oil cracked?
To make alkenes, to make alkenes with smaller molecules, to make fuels that are more useful or for which there is more demand.Large hydrocarbons do not burn easily or are less in demand
Is Hydrogenation is used to convert alkenes and alkynes to alkanes?
True
What are the real life applications of alkene?
alkenes can be polymerized into polymers (plastics), or used as fuels.
What is the process when alkenes are used to make polymers?
Lots of smaller alkene molecules are joined together to form a long chain molecule and create a polymer.
What do you use alkenes for?
alkenes are used to make polycarbonates such as polyethene which is used in making rope, plastics, etc.
Why are alkenes from alcohols not used on an industrial scale?
Since alcohols are obtained by hydration of alkenes, it is meaningless to manufacture alkenes from alkanes. Moreover, cracking hydrocarbons is a more effective and economical to make alkenes. Shawkat
What does cornstarch do as a polymer?
Cornstarch polymers are polymers made from alkenes that are mixed with cornstarch so that they are easily biodegradeable. They are used for plastic bags so that they when they are sent to a landfill site, they biodegrade quickly and easily.

What are short molecules used to make polymers?
monomers
Why are polymers used in health care?
They are used to make containers for medicines and also equipment.
What is the purpose of polymers?
Polymers are used all around, plastics and rubber are polymers.
What is an acetamidoacrylate?
An acetamidoacrylate is the acetamido derivative of an acrylate, used to make specialist polymers.
Can pt and pd be used in the hydrogenation of alkenes?
Pt and Pd can be used as catalyst in the hydrogenation of alkenes or (de)hydrogenation of hydrocarbons (cracking in petrol industry)
Are monomers made up of many polymer units?
No. Amino acid monomers are used to make protein polymers. Nucleotide monomers are used to make DNA polymers.
