Chii chinonzi Polymerization?

Polymerization ndeyekuita kwemakemikari umo monomers (mamorekuru madiki) anosanganiswa kuita polymer (morekuru). Iyi nzira inosanganisira kuumbwa kwezvisungo zvecovalent pakati pemamonomers, zvichiita kuti pave neketani-yakafanana nechimiro chine kudzokorora zvikamu.

Polymerization inogona kuitika kuburikidza nenzira dzakasiyana siyana, kusanganisira kuwedzera polymerization uye condensation polymerization. Pamusoro pe polymerization, mamonomers anobatanidzwa pamwechete kuburikidza nekutevedzana kwemakemikari maitiro anowedzera monomer imwe panguva kune iri kukura polymer cheni. Iyi nzira inowanzoda kushandiswa kwechigadziriso kuti utange kuita. Mienzaniso yekuwedzera mapolymers anosanganisira polyethylene, polypropylene, uye polystyrene.

Condensation polymerization, kune rumwe rutivi, inosanganisira kubviswa kwemorekuru diki, senge mvura kana doro, sekusangana kwemamonomers kugadzira iyo polima. Izvi zvinowanzoda mhando mbiri dzakasiyana dzemonomers, imwe neimwe iine boka rinoshanda rinogona kuumba chisungo chakabatana nemumwe. Mienzaniso yemapolymers ekugadzirisa anosanganisira nylon, polyester, uye polyurethane.

Polymerization inoshandiswa mumhando dzakasiyana-siyana dzekushandisa, kusanganisira kugadzirwa kwepurasitiki, fiber, zvinonamira, machira, uye zvimwe zvinhu. Zvimiro zvepolymer inoguma inogona kugadzirwa nekugadzirisa mhando uye huwandu hwemamonomers anoshandiswa, pamwe nemamiriro eiyo polymerization reaction.
