Iintlobo ze-polypropylene.

Iimolekyuli zePolypropylene ziqulathe amaqela e-methyl, anokwahlulwa abe yi-isotactic polypropylene, i-atactic polypropylene kunye ne-syndiotactic polypropylene ngokwendlela amaqela e-methyl ahlelwe ngayo. Xa amaqela e-methyl ebekwe kwicala elinye le-main chain, ibizwa ngokuba yi-isotactic polypropylene; ukuba amaqela e-methyl asasazwa ngokungacwangciswanga kumacala omabini e-main chain, ibizwa ngokuba yi-atactic polypropylene; xa amaqela e-methyl ebekwe ngokwahlukeneyo kumacala omabini e-main chain, ibizwa ngokuba yi-syndiotactic. polypropylene. Kwimveliso eqhelekileyo ye-polypropylene resin, umxholo wesakhiwo se-isotactic (esibizwa ngokuba yi-isotacticity) umalunga ne-95%, kwaye okuseleyo yi-atactic okanye i-syndiotactic polypropylene. I-polypropylene resin eveliswa eTshayina ngoku ihlelwe ngokwe-melt index kunye nezongezo ezongeziweyo.

I-polypropylene ye-Atactic yimveliso ephuma kwimveliso ye-isotactic polypropylene. I-polypropylene ye-Atactic iveliswa kwimveliso ye-isotactic polypropylene, kwaye i-isotactic polypropylene yahlulwe kwi-atactic polypropylene ngendlela yokwahlula.

I-polypropylene ye-Atactic yinto ethambileyo kakhulu ye-thermoplastic enamandla okutsalwa kakuhle. Ingaphinda ivulcanized njengerabha ye-ethylene-propylene.
