Chemistry Question on Polymers
Explain structure of polyacrylonitrile.
Answer
Polyacrylonitrile (PAN) is a synthetic polymer with the repeating unit:
[-CH2-CH(CN)-]n
In this structure, the "-CH2-" represents the ethylene (C2H4) unit, "-CH(CN)-" represents the acrylonitrile (CH2=CH-CN) unit, and "n" indicates the repetition of these units to form the polymer chain.
