I-PVC ibiphantsi kohlaselo oluqatha kunye nolunya iminyaka emininzi, ngokuyintloko ngenxa yokunxibelelana kwayo ne-chlorine chemistry.Kuye kwaxoxwa ngabanye ukuba ngenxa yolu nxulumano aluzinzanga, nangona uninzi lwale ngxabano luqhutywe ngokweemvakalelo kunokuba lusekelwe kuhlolisiso lwezenzululwazi.Nangona kunjalo ubukho beklorini bunika uluhlu lweempawu ezizodwa zobugcisa kwiPVC eyahlula kwezinye iipolima ezininzi.Uninzi lwezi mpawu ziyaziwa kwaye zibhalwe, kwaye mhlawumbi le nto yodwa yenza ukuba i-polymer enomdla ukufunda ngokumalunga namandla ayo okuzinza.Ihlala ixesha elide ekusebenziseni kwaye kunzima ukuyichitha.Oku kuzingisa kwenze ukuba ibe yinto ekujoliswe kuyo ngabanye abakhankasi, kodwa oku kungabuzwa ukuba lelinye lawona mandla makhulu kwimbono yozinzo.Ingxelo elandelayo ivavanya-ngokwesiseko sesayensi-yintoni ukuzinza kuthetha ntoni kwishishini le-PVC kunye namanyathelo ayimfuneko aya kufuneka ukuhambisa i-polymer ezinzileyo ngokwenene.Imodeli yovavanyo enikezelweyo isekelwe kwisikhokelo seNyathelo leNdalo (TNS).Isakhelo se-TNS siseti esomeleleyo kunye nesayensi esekwe kwizixhobo ezichaza ukuzinza kwimigaqo engacacanga kunye nesebenzayo kwaye inceda imibutho ibandakanyeke kwizinto ezisebenzayo zophuhliso oluzinzileyo.Ngokukodwa, uphando lubandakanya imbali yecala lenkqubo yophuhliso oluzinzileyo olukhokelela kolu vavanyo olubandakanya inani labathengisi base-UK abahamba phambili.
