DuPont yakavakawo marabhoritari maviri ekutanga emaindasitiri muUnited States, kwavakatanga kushanda pakugadzira makemikari e cellulose, lacquers nezvimwe zvinhu zvisingaputsi. DuPont Central Research yakatangwa paDuPont Experimental Station, mhiri kweBrandywine Creek kubva kune zvigayo zveupfu zvepakutanga.  Mubvunzo: Ndechipi chinhu chinoputika icho DuPont yakavamba kugadzira sorutivi rwokuwedzera kwavo panenge pakuvamba kwezana ramakore rechi 20?
