Noocyada polypropylene.

Molecules-ka Polypropylene waxay ka kooban yihiin kooxo methyl ah, kuwaas oo loo qaybin karo isotactic polypropylene, atactic polypropylene iyo syndiotactic polypropylene sida waafaqsan habaynta kooxaha methyl. Marka kooxaha methyl-ka lagu habeeyo isla dhinaca silsiladda ugu weyn, waxaa loo yaqaan isotactic polypropylene; haddii kooxaha methyl-ka si aan kala sooc lahayn loogu qaybiyo labada dhinac ee silsiladda ugu weyn, waxaa loo yaqaan atactic polypropylene; marka kooxaha methyl-ka si is beddel ah loogu habeeyo labada dhinac ee silsiladda ugu weyn, waxaa loo yaqaan syndiotactic. polypropylene. Soo saarista guud ee resin polypropylene, waxa ku jira qaab-dhismeedka isotactic (oo loo yaqaan isotacticity) waa qiyaastii 95%, inta soo hartayna waa atactic ama syndiotactic polypropylene. Resin polypropylene-ka hadda laga soo saaro Shiinaha waxaa loo kala saaraa iyadoo loo eegayo tusmada dhalaalka iyo waxyaabaha lagu daro.

Polypropylene-ka Atactic waa wax soo saar ka soo baxa soo saarista polypropylene-ka isotactic. Polypropylene-ka Atactic waxaa lagu soo saaraa soo saarista polypropylene-ka isotactic, polypropylene-ka isotactic-na waxaa laga soocaa polypropylene-ka atactic-ka iyadoo la adeegsanayo habka kala soocidda.

Polypropylene-ka Atactic waa walxo thermoplastic ah oo aad u dabacsan oo leh xoog jilicsan. Waxa kale oo loo rogi karaa sida cinjirka ethylene-propylene.
