Ko nga ngota ngota polypropylene kei roto nga roopu methyl, ka taea te wehewehe ki te polypropylene isotactic, polypropylene atactic me te polypropylene syndiotactic kia rite ki te whakaritenga o nga roopu methyl.Ina whakaritea nga roopu methyl ki te taha kotahi o te mekameka matua, ka kiia ko te polypropylene isotactic;ki te tohatoha matapōkeretia nga roopu methyl ki nga taha e rua o te mekameka matua, ka kiia ko te polypropylene atactic;Ina whakaritea nga roopu methyl ki nga taha e rua o te mekameka matua, ka kiia ko te syndiotactic.polypropylene.I roto i te hanga whānui o te kapia polypropylene, ko te ihirangi o te hanganga isotactic (e kiia ana ko te isotacticity) he tata ki te 95%, ko te toenga he polypropylene atactic, syndiotactic ranei.Ko te kapia polypropylene e hangaia ana i Haina i tenei wa ka whakarōpūtia i runga i te tohu whakarewa me nga taapiri taapiri.
Ko te polypropylene Atactic he hua na te hanga o te polypropylene isotactic.Ka hangaia te polypropylene Atactic i roto i te hanga o te polypropylene isotactic, ka wehea te polypropylene isotactic mai i te polypropylene atactic ma te tikanga wehewehe.
Ko te polypropylene Atactic he rauemi wera wera me te kaha kaha.Ka taea hoki te whakapuru kia rite ki te rapa ethylene-propylene.
