I-Polypropylene (PP) iyi-thermoplastic eqinile, eqinile, ne-crystalline. Yenziwe nge-propene (noma i-propylene) monomer. Le resin ye-hydrocarbon ewumugqa iyi-polymer elula kakhulu phakathi kwawo wonke amapulasitiki wempahla. I-PP iza njenge-homopolymer noma njenge-copolymer futhi ingakhuliswa kakhulu ngezithasiselo. I-polypropylene eyaziwa nangokuthi i-polypropene, iyi-polymer e-thermoplastic esetshenziswa emisebenzini ehlukahlukene. Ikhiqizwa nge-polymerization ye-chain-growth kusukela ku-monomer propylene.I-Polypropylene iyingxenye yeqembu le-polyolefin futhi iyingxenye yecrystalline futhi ayiyona i-polar. Izakhiwo zayo zifana ne-polyethylene, kodwa ilukhuni kancane futhi imelana nokushisa. Yimpahla emhlophe, eqinile ngokwemishini futhi inokumelana namakhemikhali aphezulu.
