Polymerization is a chemical reaction in which monomers (small molecules) are joined together to form a polymer (large molecule). The conditions needed for polymerization include the presence of monomers, a catalyst (which can initiate or facilitate the reaction), appropriate temperature and pressure conditions, and sometimes a solvent to dissolve the monomers. Additionally, the reaction may require specific functional groups or double bonds in the monomers to enable the polymerization process to occur.

What happens in polymerisation?
According to Sci-Tech Encyclopedia, as quoted on Answers.com, The linking of small molecules (monomers) to make larger molecules. There are two primary ways this linking occurs, condensation method, and the addition method. Both require a catalyst, such as an acid, or a heat source, depending on which method is used. For a more complete discussion of this subject, see the excellent article on Answers.com For a children's version of the explanation of polymerisation, see this excellent "Making Science Fun" article: http://www.stevespanglerscience.com/experiment/00000039
What three conditions are needed for osmosis to occur?
Three conditions are needed for osmosis to occur: a semipermeable membrane that allows only water molecules to pass through, a difference in solute concentration on either side of the membrane, and a gradient in water concentration across the membrane.
What are the conditions for condensation polymerisation?
Condensation polymerization occurs when two monomers react to form a polymer, with a small molecule (often water) being produced as a byproduct. The reaction typically requires high temperatures and longer reaction times compared to addition polymerization, as well as the presence of functional groups (such as hydroxyl or carboxyl groups) on the monomers that can react to form covalent bonds.
What is the use of decene?
Decene is an alkene which is a hydrocarbon made from crude oil but with a double bond between the two carbon atoms. To make use of any alkenes which in this case is decene you could turn it into a polymer (which is a plastic). to do this you go through a process called polymerisation. At the start of polymerisation first you have your alkene which is called a monomer in this case it would be decene and you would have lots of them, then after polymerisation it would turn into polydecene- a type of plastic this plastic would be a type of use hope it answers the question!!
What are two conditions needed to crack paraffin?
Two conditions needed to crack paraffin are high temperature (around 500-900 degrees Celsius) and the presence of a suitable catalyst. Cracking breaks down larger hydrocarbon molecules like paraffin into smaller, more valuable hydrocarbons like ethylene and propylene.
What are the examples of polymerisation?
polyethylene,polyvinylchloride
How is polymerisation carried out?
There are 2 types:- Addition polymerisation is polymerisation in which monomers are joined across the double bond, for example polyethene. Condensation polymerisation is when water is lost from the two monomers for example the polymerisation of nylon, the two monomers are a diamine and dicarboxylic acid. From the amine an H goes and combines with and OH from the acid to form water. From this reaction, 2 moles of water are lostto form nylon -NH-[ ]-NH-C=O-[ ]-C=O-
What is polymerisation reaction?
Polymerisation is a process of reacting monomer molecules together in a chemical reaction to form three-dimensional networks or polymer chains.
What technology is used in the manufacturing of polythene?
Polymerisation
What is electropolymerization?
polymerisation in the presence of an electrical current
What is polymer?
nothing
When monomers join up the process is called?
polymerisation.
What process joins two monomers?
Addition polymerisation
Why was addition polymerisation given its name?
Addition polymerisation is named for the process it involves, where monomers with double or triple bonds react to form a polymer without the loss of any small molecules. In this type of polymerisation, the monomers "add" together to create long chains, hence the term "addition." This contrasts with condensation polymerisation, where small molecules are released during the reaction. The name highlights the key characteristic of the reaction mechanism.
