Answer 1

All the asking questions are nothing but polymerisation. MH₂ (CH₂) xo + OCN(CH2)₂Nco NH(CH3), Сон (сн.), А СО Mechanissa: H₂N-(CH2) x 2 + 0 = = N(CH2) x-NCO H₂N- (CH2) x n - - Ñ _(CH2) - No - oa H₂N-(CH2)x- mi-c-mt-(CH₂)x -N = cao H₂N- ((Hz) x inte H2N-(CH2)2 - MH-C-MH (CH2)2 - MH-c-mt-CH,), my, Next periphes - inte will attack anoth another molecule and a continuous process to becer to give polymer.
