1. It is manufactured by process of chemical polymerisation into thin fibre/sheet or spun into yarn.
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
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.
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?
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.
Thermal CRacking is caused by heat while catalytic cracking is not caused by heat

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-
Polymerisation is a process of reacting monomer molecules together in a chemical reaction to form three-dimensional networks or polymer chains.
Polymerisation
polymerisation in the presence of an electrical current
Addition polymerisation
polymerisation.
No, you don't get arthritus from cracking your knucles. You're not actually cracking it, you are just "poping" your bones together
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
Jailbreaking is the term used when cracking an iOS Device while Rooting is the term used for cracking an Android Device.
