Izvo zvakasvibiswa zvemimwe miti zvinowanzogadzira resin.Kare muna 1872, nyanzvi yekemisitiri wekuGermany A. Bayer akatanga kuona kuti phenol ne formaldehyde zvinogona kukurumidza kuumba mapundu matsvuku-tsvuku kana zvinhu zvinonamira pazvinopisa mumamiriro eacidic, asi hazvigoni kunatswa nenzira dzechinyakare.uye kumisa kuedza.Mushure mezana remakore rechi20, phenol inogona kuwanikwa yakawanda kubva kumarara emarasha, uye formaldehyde inogadzirwawo yakawanda sekuchengetedza, saka maitiro ezviviri izvi zvinonyanya kukwezva, uye zvinotarisirwa kugadzira zvigadzirwa zvinobatsira, kunyange zvazvo zvakawanda. vanhu vakashandisa basa rakawanda nokuda kwayo., asi haana kuwana zvinotarisirwa.
Muna 1904, Beckland nevabatsiri vake vakaitawo tsvakurudzo iyi.Chinangwa chekutanga chaive chekugadzira pendi inodzivirira inotsiva marara echisikigo.Mushure memakore matatu ekushanda nesimba, muzhizha ra1907, kwete chete insulating pendi yakabudiswa, uye yakagadzira chaiyo yakagadzirwa epurasitiki zvinhu - Bakelite, inozivikanwa se "bakelite", "bakelite" kana phenolic resin.Kamwe Bakelite akabuda, vagadziri vakakurumidza kuona kuti yaisagona chete kugadzira zvakasiyana-siyana zvemagetsi ekudzivirira zvigadzirwa, asiwo kuita zvinodiwa zvezuva nezuva.Ndinoda T. Edison nekugadzira zvinyorwa, uye munguva pfupi yakazivisa muzviziviso kuti zviuru zvezvigadzirwa zvakaitwa neBakelite., Saka kugadzirwa kweBaekeland kwakarumbidzwa se“alchemy” yezana ramakore rechi20.
Gore ra1940 risati rasvika, iyo phenolic resin ine marasha tara sechinhu chepakutanga chaigara chiri chekutanga mukubuda kweakasiyana siyana ekugadzira resin, inosvika matani anopfuura 200,000 pagore, asi kubva ipapo, nekuvandudzwa kweindasitiri yepetrochemical, polymerized synthetic resins senge polyethylene The kubuda kwe, polypropylene, polyvinyl chloride uye polystyrene yakaramba ichiwedzera.Nekuvambwa kwemafekitari makuru akawanda ane goho repagore rinopfuura 100,000 matani ezvigadzirwa izvi, ave iwo marudzi mana emasirini ekugadzira ane yakakura kubuda nhasi.
Nhasi, masisitimu ekugadzira uye ekuwedzera anogona kushandiswa kuwana zvigadzirwa zvepurasitiki kuburikidza nenzira dzakasiyana dzekuumba.Kune akawanda emhando dzemapurasitiki, uye nyika inobuda pagore ingangoita mamirioni zana nemakumi maviri ematani.Vakave zvinhu zvekutanga zvekugadzira, hupenyu uye kuvaka nyika kudzivirira.
