1. Ngwa na mmeghachi omume polymerization

4,4'-azobis(4-cyanopentanol) bụ ngwakọta azo nke enwere ike iji dị ka ihe mmalite maka mmeghachi omume polymerization. N'usoro polymerization free radical, ọ nwere ike ịgbaze iji mepụta radicals free iji malite polymerization monomer. Dịka ọmụmaatụ, na mmeghachi omume polymerization nke monomers vinyl dị ka acrylates na styrenes, ọ nwere ike ijikwa mmalite na ọnụego nke mmeghachi omume polymerization nke ọma. Radicals free nke sitere na mmebi ya nwere ike ịmalite mmeghe nke njikọ abụọ na molekul monomer, wee jikọọ na ibe ha iji mepụta agbụ polymer.

Onye mbido a nwere ụfọdụ uru, dịka inye ọnụego mmepụta radicals n'efu kwụsiri ike n'okpuru ọnọdụ okpomọkụ kwesịrị ekwesị, ka mmeghachi omume polymerization wee nwee ike ịga n'ihu nke ọma, nke na-eme ka njikọta nke polymers nwere nkesa dị warara nke molekul dị arọ.

2. Ọrụ dị na nkwadebe nke ihe eji eme ụfụfụ

A pụkwara iji ya kwadebe ihe eji eme ụfụfụ. N'ịkwadebe ihe eji eme ụfụfụ dịka polyurethane, 4,4'-azobis (4-cyanopentanol) nwere ike isonye na mmeghachi omume iji mepụta gas, ihe ndị na-eme ka ihe dị n'efu na otu ndị ọzọ na-arụ ọrụ nke sitere na mmebi ya na-enyekwa aka na njikọta na ịgwọ matrices polymer dị ka polyurethane. Mmetụta abụọ a na-eme ka ihe eji eme ụfụfụ nwee ike ịmepụta nhazi oghere otu, a pụkwara ijikwa nha na nkesa nke oghere site na ịgbanwe ọnọdụ dịka dose ha, si otú a melite ihe anụ ahụ nke ihe eji eme ụfụfụ, dị ka ibelata njupụta ihe, imeziwanye ihe ndị na-eme ka ihe dị nro na ihe na-eme ka ihe dị nro, wdg.
