I made nylon in chemistry lab just wondering if anybody can give me help?

Question

I have to answer the following questions.
1. describe chemistry of reaction
2. describe product characteristics
3. describe the main intermolecular forces acting on the polymer chain.

Any help with these questions wil be mush appreciated!
Thanks

its preparing nylon 6, 10 (poly amide)

Answer 1

I dont know u made which nylon?
nylon -6 or nylon-66

so i'm giving both.

Nylon-6
Cyclohexanone------treat by NH2OH-------gives cyclohexanoneoxime-------treat by oleum------gives caprolactam----gives nylon-6

Nylon-66:
Adipic acid + Hexamethylene diamine---heat----gives nylon 66

Above their melting temperatures, Tm, thermoplastics like nylon are amorphous solids or viscous fluids in which the chains approximate random coils. Below Tm, amorphous regions alternate with regions which are lamellar crystals. The amorphous regions contribute elasticity and the crystalline regions contribute strength and rigidity.

The planar amide (-CO-NH-) groups are very polar, so nylon forms multiple hydrogen bonds among adjacent strands. Because the nylon backbone is so regular and symmetrical, especially if all the amide bonds are in the trans configuration, nylons often have high crystallinity and make excellent fibers.

Nylon 6,6 can have multiple parallel strands aligned with their neighboring peptide bonds at coordinated separations of exactly 6 and 4 carbons for considerable lengths, so the carbonyl oxygens and amide hydrogens can line up to form interchain hydrogen bonds repeatedly, without interruption. Nylon 5,10 can have coordinated runs of 5 and 8 carbons. Thus parallel (but not antiparallel) strands can participate in extended, unbroken, multi-chain β-pleated sheets, a strong and tough supermolecular structure similar to that found in natural silk fibroin and the β-keratins in feathers. (Proteins have only an amino acid α-carbon separating sequential -CO-NH- groups.) Nylon 6 will form uninterrupted H-bonded sheets with mixed directionalities, but the β-sheet wrinkling is somewhat different. The three-dimensional disposition of each alkane hydrocarbon chain depends on rotations about the 109.47° tetrahedral bonds of singly-bonded carbon atoms.

When extruded into fibers through pores in an industrial spinneret, the individual polymer chains tend to align because of viscous flow. If subjected to cold drawing afterwards, the fibers align further, increasing their crystallinity, and the material acquires additional tensile strength. In practice, nylon fibers are most often drawn using heated rolls at high speeds.

Block nylon tends to be less crystalline, except near the surfaces due to shearing stresses during formation. Nylon is clear and colorless, or milky, but is easily dyed. Multistranded nylon cord and rope is slippery and tends to unravel. The ends can be melted and fused with a flame to prevent this.

There are carbon fiber/nylon composities with higher density than pure nylon.

i don't be attentive to approximately heroin yet cocaine is organic and processed in important and south american international places from a plant then dried and despatched into the U.S. and different international places and shrink with different factors and then resold on the streets in numerous varieties and fashions. wager you would be able to look that up and get the wonderful answer for you project.
