Which one of the following pairs is not correctly matched? a)Terylene-...
Incorrectly Matched Polymer Pairs
There are various types of polymers used in different applications. Sometimes, it becomes difficult to recognize the correct pair of polymers. Here, we are given four pairs of polymers, and we need to identify the pair that is not correctly matched.
Terylene
Terylene is a condensation polymer of terephthalic acid and ethylene glycol. It is commonly used in the production of clothing, plastic bottles, and films.
Teflon
Teflon is a thermally stable cross-linked polymer of phenol and formaldehyde. It is used in non-stick coatings, gaskets, and seals.
Perspex
Perspex is a homopolymer of methyl methacrylate. It is a transparent plastic used in the production of signs, displays, and light fixtures.
Synthetic Rubber
Synthetic rubber is a copolymer of butadiene and styrene. It is used in tire manufacturing, industrial hoses, and conveyor belts.
Incorrectly Matched Pair
The pair that is not correctly matched is Teflon-thermally stable cross-linked polymer of phenol and formaldehyde.
Teflon is not a cross-linked polymer of phenol and formaldehyde. Instead, it is a polymer of tetrafluoroethylene. Teflon is known for its non-stick properties and resistance to high temperatures. It is used in various applications, including cookware, electrical insulation, and aerospace industries.
Conclusion
In summary, Teflon-thermally stable cross-linked polymer of phenol and formaldehyde is the pair that is not correctly matched. The other pairs, Terylene, Perspex, and Synthetic rubber, are correctly matched with their respective polymers.

Hey guys cool question
TEFLON IS TETRA FLOURO ETHENE
CF2=CF2
WELL KNOWN
BAKELITE IS PHENOL+FORMALDEHYDE
