Ko te waikawa adipic, e mohiotia ana ko te waikawa ngako, he waikawa dibasic waro nui e whai waahi nui ana ki nga momo ahumahi. Ma te tauira hanga o HOOC(CH2)4COOH, ka taea e tenei puhui whai kiko te pa ki nga tauhohenga maha penei i te hanga tote, te whakamaarama, me te amidation. I tua atu, he kaha ki te polycondense me te diamine, te diol ranei hei hanga i nga waerau ngota teitei. He nui te uara o tenei waikawa dicarboxylic-ahumahi ki te hanga matū, te ahumahi whakahiato pararopi, te rongoa, me te whakahinuhinu. Ko tana hiranga kaore e taea te whakakorehia ka kitea i roto i tana tuunga hei tuarua o te waikawa dicarboxylic tino whakaputa i te maakete.
