"monomer "

they repeat to form a long chaine  macromelecule ( polymer )

monomers are in all polymers < everything has a different monomer

poly ( ETHEENE ) has ethene monomer
poly ( propene ) has propmene monemer 

ethene and propene are the repeating units


in the case  CONDESATION polymerisation

there is a repeating unit for nylon ( DIAMINE+ DICARBOXILYIC ACID )
there is a repeating unit for terylene (  DIOL + DICARBOXYILC ACID )

Oh, so repeating units are just monomers? Ryte :) Thanks a lot once again.. ;D
