     [NH(CH2) NHCO (CH2)4 CO]n is a: [AIPMT (S) 2006]

    A) co-polymer        

    B) addition polymer

    C) thermo-setting polymer               

    D) homopolymer

    Correct Answer: B

    Solution :

    [b] \[-[NH{{(CH)}_{2}}NHCO{{(C{{H}_{2}})}_{4}}CO]{{-}_{n}}\] is a copolymer because polymers whose repeating structural units are derived form two or more types of monomer units are called copolymer. \[n{{H}_{2}}N{{(C{{H}_{2}})}_{2}}N{{H}_{2}}+nHOOC{{(C{{H}_{2}})}_{4}}COOH\]
                \[\xrightarrow[-n{{H}_{2}}O]{Polymerisation}-\left[ NH(C{{H}_{2}}){{ & }_{2}}NHCO{{(C{{H}_{2}})}_{4}}CO \right]{{-}_{n}}\]
