I tata nei, ko te metallocene polypropylene whakakōkī motuhake whakawhanakehia e te Beijing Research Institute o Ahumahi matū oti pai te whakamātautau tono ahumahi tuatahi i roto i te mowhiti paipa polypropylene wae tukanga o Zhongyuan Petrochemical, a hanga homopolymerized me matapōkere copolymerized kapia metallocene polypropylene me te mahi pai. Ko Haina Sinopec te kamupene tuatahi i Haina ki te whakawhanake motuhake i te hangarau polypropylene metallocene.
Ko te Metallocene polypropylene nga painga o te iti o te wairewa, te maamaatanga teitei me te kanapa teitei, he huarahi nui mo te whakarereke me te whakahou i te umanga polypropylene me te whanaketanga teitei. I timata a Beihua Institute i te rangahau me te whakawhanaketanga o te metallocene polypropylene catalyst i te tau 2012. I muri i te whakamatautau iti, te whakamatautau tauira me te whakamatautau pairati te whakarite tauine-ake, ka whakatauhia e ia nga raruraru hangarau penei i te hoahoa hanganga whakakōkī, te tukanga whakarite me te arotautanga mahi catalytic, me te pai te whakawhanake i te metallocene polypropylene catalyst. Hangarau propylene catalyst me te hanga o nga hua whakakorikori. I roto i te arotakenga whakatairite i raro i nga tikanga polymerization ano, he nui ake te mahi o te whakakorikori i te whakakorikori kawemai, a, he pai ake te ahua matūriki o te hua polypropylene kua rite, kaore he agglomeration.
Mai i te Whiringa-a-rangi i tenei tau, kua oti nga whakamatautau ahumahi i roto i te Hypol tukanga polypropylene tipu o Yangzi Petrochemical me te tukanga mowhiti polypropylene tipu o Zhongyuan Petrochemical, a ka whiwhi hua manatoko pai. Ko tenei whakamatautau ahumahi i Zhongyuan Petrochemical ko te wa tuatahi ki Haina ki te whakaputa matapōkeretia copolymerized metallocene polypropylene i runga i te mowhiti paipa polypropylene taputapu, kua whakatakoto he turanga pakari mo te whanaketanga teitei o te ahumahi polypropylene a Sinopec.
