Izinhlobo ze-polypropylene .

Ama-molecule e-polypropylene aqukethe amaqembu e-methyl, angahlukaniswa abe yi-isotactic polypropylene, atactic polypropylene kanye ne-sydiotactic polypropylene ngokuvumelana nokuhlelwa kwamaqembu e-methyl.Lapho amaqembu e-methyl ehlelwa ohlangothini olufanayo lweketango eliyinhloko, libizwa ngokuthi i-isotactic polypropylene;uma amaqembu e-methyl esatshalaliswa ngokungahleliwe ezinhlangothini zombili zeketango eliyinhloko, kubizwa ngokuthi i-atactic polypropylene;lapho amaqembu e-methyl ehlelwa ngokushintshana ezinhlangothini zombili zeketango eliyinhloko, ibizwa ngokuthi i-sydiotactic.i-polypropylene.Ekukhiqizweni okujwayelekile kwe-polypropylene resin, okuqukethwe kwesakhiwo se-isotactic (okubizwa ngokuthi isotacticity) cishe ku-95%, kanti enye i-atactic noma i-sydiotactic polypropylene.I-polypropylene resin ekhiqizwa eChina njengamanje ihlukaniswa ngokwenkomba yokuncibilika kanye nezithasiselo ezingeziwe.

I-Atactic polypropylene ingumkhiqizo wokukhiqizwa kwe-isotactic polypropylene.I-Atactic polypropylene ikhiqizwa ekukhiqizeni i-isotactic polypropylene, futhi i-isotactic polypropylene ihlukaniswa ne-atactic polypropylene ngendlela yokuhlukanisa.

I-Atactic polypropylene iyinto enwebeka kakhulu ye-thermoplastic enamandla aqinile.Ingase futhi ihlanzwe njengerabha ye-ethylene-propylene.
