1. Ngwa na mmeghachi omume polymerization

4,4'-azobis (4-cyanopentanol) bụ ngwakọta azo nke enwere ike iji dị ka onye mmalite maka mmeghachi omume polymerization. Na usoro nke free radical polymerization, ọ nwere ike decompose na-emepụta free radicals na-amalite monomer polymerization. Dịka ọmụmaatụ, na mmeghachi omume polymerization nke vinyl monomers dị ka acrylates na styrenes, ọ nwere ike ịchịkwa mmalite na ọnụego nke mmeghachi omume polymerization. The free radicals mepụtara site nbibi ya nwere ike ibido oghere nke abụọ agbụ na monomer molecules, na mgbe ahụ jikọọ na onye ọ bụla ọzọ na-emepụta polymer chains.

Onye mmalite a nwere uru ụfọdụ, dị ka ịnye ọnụ ọgụgụ ọgbọ na-akwụsi ike n'efu n'okpuru ọnọdụ okpomọkụ kwesịrị ekwesị, nke mere na mmeghachi omume polymerization nwere ike ịga n'ihu nke ọma, nke na-eme ka njikọ nke polymers na nkesa dị arọ dị warara.
