E rua ngā momo matua o te polypropylene e wātea ana: ko ngā homopolymer me ngā copolymer. Ka wehea anō ngā copolymer ki ngā copolymer poraka me ngā copolymer matapōkere.
He pai ake te uru o ia kāwai ki ētahi tono i ētahi atu. E kiia ana te polypropylene ko te "maitai" o te umanga kirihou nā te maha o ngā huarahi ka taea te whakarerekē, te whakarite rānei kia pai ai te whakatutuki i tētahi kaupapa motuhake.
Ko te tikanga ka tutuki tēnei mā te tāpiri i ngā tāpiringa motuhake ki roto, mā te hanga rānei i roto i tētahi huarahi tino motuhake. He āhuatanga nui tēnei urutau.
Polypropylene homopolymerhe momo whānui. Ka taea e koe te whakaaro ki tēnei hei āhua taunoa o te rauemi polypropylene.Poraka kōporemuHe poraka ngā waeine co-monomer o te polypropylene (arā, he tauira auau) ā, kei roto i tēnā he 5% ki te 15% ethylene.
Ka whakapai ake te ethylene i ētahi āhuatanga, pērā i te ātete ki te pānga, ā, ka whakarei ake ētahi atu tāpiringa i ētahi atu āhuatanga.
Copolymer matapōkereKo te polypropylene – he rerekē ki te polypropylene copolymer poraka – kei a rātou ngā waeine co-monomer kua whakaritea kia koretake, kia matapōkeretia rānei i te taha o te ngota polypropylene.
I te nuinga o te wā ka whakauruhia ki roto i ēnei te 1% ki te 7% ethylene, ā, ka tīpakohia mō ngā whakamahinga e hiahiatia ana he hua mārama ake, he ngāwari ake te whakakorikori.
