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 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.
