Which of the following are the monomers of “Glyptal” polymer ?

Monomers of “Glyptal” Polymer

Polymers have two key characteristics. The first is a polymer’s physical property, while the second is a polymer’s chemical property.

• Physical Properties: The tensile strength of the polymer increases along with cross-linking & chain length. Polymers do not melt; instead, they transition from a crystalline to a semi-crystalline form.

• Chemical Properties: Ionic and hydrogen bonding are enabled in the polymer, improving crosslinking strength. The polymer’s remarkable flexibility is made possible by side chains that form dipole-dipole bonds. Although known to be weak, polymers containing Van der Waals forces connecting chains have a low melting point.

The Commercial Uses of Polymers are displayed in the table below along with the corresponding monomers.

Polymer	Uses of Polymer	Monomer
BUNA-N	Synthetic rubber	1, 3-butadiene Vinyl Cyanide
Glyptal	Fabric, making paints, coatings	Ethylene glycol Phthalic acid
Rubber	Making tires, elastic materials	Isoprene (1, 2- methyl 1 – 1, 3-butadiene)
Bakelite	Plastic switches, Mugs, buckets	Phenol Formaldehyde
Nylon-6	Fabric	Caprolactam

Summary:

Which of the following are the monomers of “Glyptal” polymer ? (a) Ethylene glycol & Phthalic acid (b) 1, 3-butadiene & Vinyl Cyanide (c) Ethylene glycol & Terephthalic acid (d) Caprolactum

Ethylene glycol and terephthalic acid are the monomers that make up the “Glyptal” polymer. A molecule that connects with the other molecule and reacts together is called a monomer. Example – Glucose, amino acids, etc.
