2. Nylon is a synthetic polymers, more specifically aliphatic or semi-aromatic polyamides and they polyfunctionality and thermoplastic. They can be melt-processed into fibers, films or shapes Types of nylon The most common type of Nylon are Cast Nylon (Type 6) and Extruded Nylon (Type 6,6) Monomer nylon 6 is only made from one kind of monomer, a monomer called caprolactam. Nylon 6,6 is made from two monomers, adipoyl chloride and hexamethylene diamine Molecular formula (C6H11NO)n Polymerization method condensation polymerization

3. Physical and chemical properties of nylon Density: 1.14 gm /c.c. Elongation at break: 15 – 45% Elasticity: Very good . Resiliency: Good. Melting point: 215 C. Ability to protest friction: Excellent Glass transition temperature: 45-60 C
