Condensation polymers are obtained by bifunctional molecules (monomers) with the elimination of smaller molecules whereas additional polymers are obtained from multiple bonds containing monomers. Neoprene is a polymer of chloroprene (CH2 =C(Cl)-C=CH2) so it is an addition polymer, not a condensation polymer.
