Nylon For Pharmacognosy Submitted by: Thandolwenkosi Pride 11215609

PowerPoint Presentation:

Nylon is the generic designation for a family of synthetic polymers known as Aliphatic polyamides. It is a polymer of adipic acid and hexamethylene diamine . Nylon is made of units linked by amine bonds an is referred to as polyamide

Synthesis o f nylon:

Synthesis o f nylon Molecules with an acid (-COOH) group on each en are reacted with molecules containing amine (-NH ₂ ). Properties are determine by the R an R’

PowerPoint Presentation:

Overal equation: Nylon 6,6 6C 6C

PowerPoint Presentation:

The two monomers are benzene-1,4-dicarboxylic acid and 1,4-diaminobenzene 35.3 Synthetic Polymers (SB p.171) water molecules are eliminated

PowerPoint Presentation:

Hydrogen Bond in Nylon


Characteristics Variation of luster Durability High elongation Excellent abrasive resistance High resistance


Characteristics Excellent resistance to oils, Bases Limited resistance to dilute acid Tough, strong an impact resistant material Abrasion resistant.

Hydrolysis and degradation:

Hydrolysis and degradation All nylons are susceptible to hydrolysis an the reaction is the reverses of the synthesis.


Uses It is used for making fishing nets, ropes, parachutes and type cords. It is used for making fabrics in textile industry. Nylon is widely used as plastic for making machine parts. It is blended with wool to increase the strength.
