Question

What bonds are broken and what bonds are formed in the synthesis of:

a.Nylon 66

b.Glyptal

c.Cross-linked PVA

Answer 1

Nylon 6,6:

Nylon 6,6 is made up of adipic acid and hexmethylene diamine where C-O bond N-H bond will be broken. Water molecule get eliminated. C-N will be formed.

Glyptal :

Phthalic anhydride and Glecerol are reacting together giving Glyptol where where C-O bond O-H bond will be broken. C-O will be formed.

Cross-linked PVA:

Cross-linked PVA is made from clevage of polyvinyl acetate which synthesised from vinyl acetate. Where C=C will be broken and C-C is made
