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.
