What is the repeating unit in the condensation polymer obtained by combining HOOC-CH2-CH2-COOH (succinic acid) & H2N-CH2-CH2-NH2 (ethylenediamine)
When succinic acid react with ethylenediamine, it form nylon type polymers.
HOOC-CH2-CH2-COOH + H2N-CH2-CH2-NH2 →HOOC-CH2-CH2-CO-HN-CH2-CH2-NH2 + H2O
The repeating unit is –(-OC-CH2-CH2-CO- HN-CH2-CH2-NH-)-
