How is Nylon manufacturing process?
1. It is manufactured by process of chemical polymerisation into thin fibre/sheet or spun into yarn.
What is condensation polymerisation?
Condensation polymerisation is when two molecules of the same substance (monomer) react together to form polymer chain (like polythene) and eliminate a smaller (usually water) molecule. For example, Nylon-6 is prepared by using condensation polymerisation of ε-Caprolactum
How do expansion joints in a sidewalk keep the concrete from cracking?
The expansion joint in a sidewalk keeps the concrete from cracking just as what its called. It allows the concrete to expand when heated and contract when cold. Without the joint, the concrete will crack and become uneven or mountain up.
What is a loop reactor?
A bulk (slurry) polymerisation reactor which is made of a closed long tube through which the slurry is circulated. Loop reactors are characterised by a very narrow residence time distribution, leading to uniform product characteristics.

What is the difference between call centre and bpotc?
What are the differences between cracking and polymerisation?
Cracking is a process in which larger hydrocarbon molecules are broken down into smaller ones by heat and pressure, often used to produce gasoline. Polymerization is a process in which smaller molecules, called monomers, are chemically joined together to form larger molecules called polymers, used to create plastics and synthetic materials. In summary, cracking breaks molecules apart while polymerization joins molecules together.
What is difference between thermal and catalytic cracking?
Thermal CRacking is caused by heat while catalytic cracking is not caused by heat
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
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.
Does cracking knuckles cause arthritus?
No, you don't get arthritus from cracking your knucles. You're not actually cracking it, you are just "poping" your bones together
Who invented computer cracking?
originally computer cracking was to test computer is different situations. previous to that people would use hacking/cracking to fool telephone exchanges to get free phone calls etc
