Ukwenza kakuhle kuyilo nakwimveliso yeplastiki, kufuneka siziqonde iindidi kunye nokusetyenziswa kweplastiki. Iplastiki luhlobo lwekhompawundi ephezulu yemolekyuli (ii-macrolecule) ezifakwa ipolymerized ngokudibanisa i-polymerization okanye i-polycondensation reaction nge-monomer njengezinto ezingavuthiyo. Zininzi izihlobo ...Funda ngokugqithisileyo »
