Unugyada Polypropylene waxaa ku jira kooxo methyl ah, kuwaas oo loo qaybin karo polypropylene isotactic, polypropylene atactic iyo polypropylene syndiotactic sida waafaqsan habaynta kooxaha methyl. Marka kooxaha methyl lagu habeeyo isla dhinaca silsiladda ugu weyn, waxaa loo yaqaan polypropylene isotactic; haddii kooxaha methyl si aan kala sooc lahayn loogu qaybiyo labada dhinac ee silsiladda ugu weyn, waxaa loo yaqaan 'polypropylene atactic'; marka kooxaha methyl si kala duwan loo habeeyo labada dhinac ee silsiladda ugu weyn, waxaa loo yaqaan syndiotactic. polypropylene. Wax soo saarka guud ee resin polypropylene, waxa ku jira qaab-dhismeedka isotactic (oo loo yaqaan isotacticity) waa qiyaastii 95%, inta soo hartayna waa polypropylene atactic ama syndiotactic. Xabagta polypropylene ee hadda laga soo saaro Shiinaha waxaa loo kala saaray iyadoo loo eegayo tusmada dhalaalka iyo waxyaabaha lagu daro.
Atactic polypropylene waa ka-soo-saarka wax-soo-saarka polypropylene isotactic. Atactic polypropylene waxaa lagu soo saaraa soo saarista polypropylene isotactic, iyo polypropylene isotactic waxaa laga soocaa polypropylene atactic iyadoo loo marayo habka kala soocida.
Atactic polypropylene waa shey heerkulbeeg heer sare ah leh oo leh awood adag oo wanaagsan. Waxa kale oo ay noqon kartaa vulcanized sida cinjirka ethylene-propylene.
