I-Polypropylene (PP) yi-thermoplastic eqinile, eqinile, kunye ne-crystalline. Yenziwe kwi-propene (okanye ipropylene) i-monomer. Le ntlaka yomgqa wehydrocarbon yeyona polima ikhaphukhaphu kuzo zonke iiplastiki zemveliso. I-PP iza njenge-homopolymer okanye njenge-copolymer kwaye inokunyuswa kakhulu kunye nezongezo. Ipolypropylene ekwabizwa ngokuba yi-polypropene, yipolymer ye-thermoplastic esetyenziswa kwiintlobo ngeentlobo zezicelo. Iveliswa nge-chain-growth polymerization ukusuka kwi-monomer propylene.I-Polypropylene yeyeqela le-polyolefins kwaye i-crystalline ngokuyinxenye kunye ne-non-polar. Iipropathi zayo zifana ne-polyethylene, kodwa inzima kancinci kwaye iyamelana nobushushu. Yimathiriyeli emhlophe, enoomatshini kwaye inokumelana nemichiza ephezulu.
