i) Name the polymer whose partial structure is represented by
ii) What are the monomers of Nylon 6, 6 ? 

Explanation

a) i) It si prepared by addition polymerisation of acrylonitrite in presence of peroxide catalyst
The partial structure polymer is

ii) The monomers present in nylon 6, 6 is
1) Hexa methylene diamine `NH_(2)-(CH_(2))_(6)-NH_(2)`
2) Adipic acid `HOOC - (CH_(2))_(4)-COOH`
These two monomers undergoes (copolymerisation) condensation polymerization to form nylon - 66
i.e.,
`underset("Henametylene dumine")(NH_(2)-(CH_(2))_(6)-NH_(2))+underset("Adipic acid")(HOOC-(CH_(2))_(4)-COOH)rarr underset("Nylon - 66")([NH-(CH_(2))_(6)-NH-overset(O)overset(||)C-(CH_(2))_(4)-overset(O)overset(||)C-]_(n))`
