Explanation
Chain growth polymer is also known as addition polymer. A chain growth polymer is a polymer which is formed when molecules of the same monomer or different monomers add together on a large scale to form the poly mer. Out of the given polymers, Teflon is a chain growth polymer as the molecules of tetrfluoroethene (monomer) simply add together to form the polymer.
PHBV [poly- β -hydroxy butyrate –CO- β - hydroxy-valerate ] is a biodegradable polymer.
The biodegradable polymer is cellulose, because many types of microorganisms are known to biodegrade cellulose. Bacteria and fungi are of particular interest because they are the most widely available degrading microorganisms.
Bakelite is formed from a condensation reaction of phenol with formaldehyde and it is a cross–linked polymer.
Neoprene is a synthetic polymer which resembles natural rubber, and it is resistant to oil , heat and weathering.
A thermosetting polymer also Known as thermoset. IUPAC defines a thermo setting rerin as a prepolymer in a soft solid or viscous state that changes irrevessibly into an infusible, in soluble polymer network by curing. The curing process transforms the resin into a plastic or rubber by a cross-linking process in to a 3-D structure.
The catalyst used for the polymerization of olefin is Zeigler-Natta catalyst. [Al(C2H5)3 + TiCl4]
