Question

Super glue is a polymer of
A.Terephthalic acid chloride
B.Ethylene chloride
C.Acrylonitrile
D.Methyl $\alpha$ -cyanoacrylate

Answer 1

We must remember that the super glue is a fast adhesive and forms a strong bond. Super glue consists of repeating monomers. Before super glue polymerizes, it has double bonds that can be stolen if exposed to anions. This sets off a chain reaction that binds the super glue. Super glue is a great tool for holding things together.

Complete answer:
Let’s first all study the properties of all the options to give an answer.
Let we discuss about the details of terephthalic acid chloride as,
It is the hydrochloric acid of terephthalic acid and one of the two monomers used to make Kevlar (R), the other being p-phenylenediamine. Terephthalic acid chloride-is used to make various copolymers and aramid polymers such as Heracron and Kevlar. Therefore, the option A is incorrect.
Now we can discuss about the ethylene chloride as,
The most common use of Ethylene is manufacture of pipes, furniture and automobiles from polyvinyl chloride (PVC) and fabrics. Coating, Wall coverings, household goods and auto parts. $1,2 - Dichloroethane$ Is also used as an intermediate for other organic compounds and as a solvent. It forms an azeotrope with many other solvents, including water. Hence the option B is incorrect.
Now we discuss the details of acrylonitrile as,
Acrylonitrile is an organic compound. Due to its molecular structure, it consists of a vinyl group attached to a nitrile. Acrylonitrile is mainly used as a monomer to make polyacrylonitrile, homopolymers, or some important copolymers such as styrene-acrylonitrile (SAN), acrylonitrile-butadiene-styrene (ABS), acrylonitrile-styrene-acrylate (ASA) and other synthetic rubbers such as acrylonitrile.
Now we can discuss about the details of cyanoacrylate as,
In its simplest form, cyanoacrylate can be considered a super glue - a transparent glue that dries quickly and is very sticky. In the form of polymer resin (plastic resin) in cured form and monomer in the form of not preserved.
Cyanoacrylates are mainly used as adhesives. The thin layers are joined effectively and the thick layers are less. They bind to many substances, including human skin and tissue, natural fibres, cotton, wool, and leather.
The cyanoacrylate adhesive has low shear strength, which results in it being used as a temporary adhesive if the pieces need to be cut later. Common examples include assembling the part on a sacrificial lathe adhesive block and fixing pins and bolts. It is also used in conjunction with other slower but tougher adhesives to quickly form bonds which then hold the parts in the appropriate configuration until the second adhesive has cured.
Now it’s clear from the above points that Super glue is a polymer of Methyl $\alpha$ -cyanoacrylate.

So, the correct answer is Option D.

Note: Now we discuss about the properties and uses of cyanoacrylate as,
1. Cyanoacrylate is not Super Glue, but superglue is cyanoacrylate. Some types of cyanoacrylate are commonly referred to as super glues because they identify the properties of the direct, strong bonds known to people.
2. Cyanoacrylate is a very strong adhesive, especially when used to bond materials that are not porous or that contain a small trace of water. It is also very good at holding body tissues together and while this can be an annoying side effect as long as daily use has been used for a smooth operation.
3. Cyanoacrylate based adhesives have weak bonds with smooth surfaces and, as such, are prone to friction; A good example of this is the fact that cyanoacrylate can be removed from human skin with the help of an abrasive (e.g. sugar or sandpaper).
