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 polypropylene resin, 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 mahia ana i Haina i tenei wa ka whakarōpūtia i runga i te taurangi 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 papanga wera wera me te kaha kaha. Ka taea hoki te whakapuru kia rite ki te rapa ethylene-propylene.
