Izinhlobo ze-polypropylene.

Ama-molecule e-polypropylene aqukethe amaqembu e-methyl, angahlukaniswa abe yi-isotactic polypropylene, i-atactic polypropylene kanye ne-syndiotactic polypropylene ngokwendlela amaqembu e-methyl ahlelwe ngayo. Lapho amaqembu e-methyl ehlelwe ohlangothini olufanayo lwe-main chain, ibizwa ngokuthi i-isotactic polypropylene; uma amaqembu e-methyl esatshalaliswa ngokungahleliwe kuzo zombili izinhlangothi ze-main chain, ibizwa ngokuthi i-atactic polypropylene; lapho amaqembu e-methyl ehlelwe ngokushintshana kuzo zombili izinhlangothi ze-main chain, ibizwa ngokuthi i-syndiotactic. polypropylene. Ekukhiqizweni okuvamile kwe-polypropylene resin, okuqukethwe kwesakhiwo se-isotactic (esibizwa ngokuthi i-isotacticity) cishe kungama-95%, kanti okusele kuyi-atactic noma i-syndiotactic polypropylene. I-polypropylene resin ekhiqizwa eShayina njengamanje ihlukaniswa ngokwe-melt index kanye nezithasiselo ezengeziwe.

I-polypropylene ye-Atactic iwumkhiqizo ongaphansi kokukhiqizwa kwe-polypropylene ye-isotactic. I-polypropylene ye-Atactic ikhiqizwa ekukhiqizweni kwe-polypropylene ye-isotactic, kanti i-polypropylene ye-isotactic ihlukaniswa ne-polypropylene ye-atactic ngendlela yokuhlukanisa.

I-polypropylene ye-Atactic iyinto ethambile kakhulu ye-thermoplastic enamandla amakhulu okuthambekela. Ingaphinde ivundiswe njengerabha ye-ethylene-propylene.
