Ngawo-1960, ama-polymers amunca kakhulu atholakala enezindawo ezinhle kakhulu zokumunca amanzi futhi asetshenziswa ngempumelelo ekukhiqizeni amanabukeni ezingane. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, ukusebenza kwe-polymer emunca kakhulu nakho kuye kwathuthukiswa nakakhulu. Kulezi zinsuku, isiphenduke into enekhono lokumunca amanzi amaningi nokuzinza, esetshenziswa kabanzi kwezokwelapha, ezolimo, ukuvikelwa kwemvelo, kanye nezimboni, okuletha ukunethezeka okukhulu ezimbonini ezahlukahlukene.
