Polymerization ke eng?

Polymerization ke karabelo ea lik'hemik'hale moo li-monomers (limolek'hule tse nyane) li kopantsoeng ho etsa polymer (molek'hule e kholo). Ts'ebetso ena e kenyelletsa ho theha maqhama a covalent pakeng tsa li-monomers, tse hlahisang sebopeho se kang ketane se nang le likarolo tse pheta-phetoang.

Polymerization e ka etsahala ka mekhoa e fapaneng, ho kenyelletsa polymerization le condensation polymerization. Ntle le moo polymerization, li-monomers li kopantsoe hammoho ka letoto la karabelo ea lik'hemik'hale tse eketsang monomer e le 'ngoe ka nako ho ketane e ntseng e hola ea polymer. Ts'ebetso ena hangata e hloka tšebeliso ea sesebelisoa ho qala karabelo. Mehlala ea ho eketsa li-polymers li kenyelletsa polyethylene, polypropylene, le polystyrene.

Ka lehlakoreng le leng, condensation polymerization e kenyelletsa ho felisoa ha molek'hule e nyane, joalo ka metsi kapa joala, joalo ka ha li-monomer li kopana ho etsa polymer. Ts'ebetso ena hangata e hloka mefuta e 'meli e fapaneng ea li-monomers, e' ngoe le e 'ngoe e na le sehlopha se sebetsang se ka etsang maqhama a covalent le se seng. Mehlala ea li-polymer tsa condensation li kenyelletsa nylon, polyester le polyurethane.

Polymerization e sebelisoa mesebetsing e mengata e fapaneng, ho kenyelletsa tlhahiso ea lipolasetiki, likhoele, likhomaretsi, liphahlo le lisebelisoa tse ling. Thepa ea polymer e hlahisoang e ka hlophisoa ka ho fetola mofuta le palo ea li-monomers tse sebelisitsoeng, hammoho le maemo a karabelo ea polymerization.
