Solution

<ul> <li><strong>Nylon-2-Nylon-6</strong> is a biodegradable polymer. It is made from two monomers, hexamethylenediamine and adipic acid. The polymer is strong and durable, but it can also be broken down by bacteria and other microorganisms. This makes it a good choice for use in products that are designed to be biodegradable, such as food packaging and medical implants.</li><br/> <li><strong>Buna N</strong> is a synthetic rubber. It is made from a mixture of 1,3-butadiene and acrylonitrile. The polymer is strong and flexible, and it is resistant to wear and tear. Buna N is used in a variety of applications, including tires, hoses, and belts.</li><br/> <li><strong>Urea-formaldehyde</strong> is a thermosetting resin. It is made from a mixture of urea and formaldehyde. The polymer is hard and strong, and it is resistant to heat, water, and chemicals. Urea-formaldehyde is used in a variety of applications, including adhesives, coatings, and foams.</li><br/> <li><strong>Dacron</strong> is a polyester. It is made from a mixture of terephthalic acid and ethylene glycol. The polymer is strong, durable, and lightweight. Dacron is used in a variety of applications, including clothing, fabrics, and bottles.</li> </ul>
