Usoro mmepụta
Usoro 1: Usoro hydrolysis
Nkeacrylamideenwetara site na usoro hydrolysis nwere nkesa acrylamide mgbe niile na agbụ macromolecular.Pasent molar nkeacrylamideagbụ na agbụ macromolecular bụ ogo nke hydrolysis.
E jiri ya tụnyere usoro copolymerization, ihe na-egbochi dandruff na-edozi mmiri (HD) nke ngwaahịa ndị a kwadebere site na usoro hydrolysis n'ozuzu adịghị elu, ihe na-erughị 30%.N'ụzọ doro anya, ngwaahịa ndị nwere HD karịa 70% kwesịrị ịdị njikere site na usoro copolymerization, nke nwere ụfọdụ ihe achọrọ na okpomọkụ hydrolysis na ihe omume, ma na-enwekarị mbibi macromolecular n'oge usoro hydrolysis.
Usoro 2: Polymerization nke ngwọta mmiri
Aqueous ngwọta polymerization polymerization nke mmeghachi omume monomer na onye mmalite na-etisasịwo na mmiri.Usoro a dị mfe, obere mmetọ gburugburu ebe obibi, mkpụrụ nke polymer dị elu, dị mfe ịnweta polymer dị arọ dị elu, bụ usoro mbụ eji eme ihe na mmepụta nke polyacrylamide, ma bụrụ ụzọ bụ isi nke mmepụta ihe mmepụta ihe nke polyacrylamide.A mụọla nke ọma polymerization nke ngwọta mmiri.
Usoro 3: polymerization emulsion na-atụgharị
Reverse-adọ colloidal dispersion usoro kwesịrị ka a kwadebere tupu tụgharịa-adọ emulsion polymerization na tụgharịa-adọ nkwusioru polymerization, ya bụ, mmiri / mmanụ (W / 0) heterogeneous dispersion usoro na-guzobere na mmanụ na-adọ nke monomer aqueous ngwọta site na-akpali dispersion. ma ọ bụ emulsifier, wee tinye onye mbido maka polymerization n'efu.
N'ozuzu, ndị initiators soluble mmanụ na-eji na-atụgharị-phase emulsion polymerization, ukwuu n'ime anionic free radical initiators na-abụghị ionic free radical initiators, ebe ntughari-phase nkwusioru polymerization na-eji mmiri soluble initiators, dị ka persulfate.Enwere echiche abụọ na usoro nucleation nke AM / AA tụgharịrị emulsion polymerization: nucleation micellar na monomer droplet nucleation.The kinetics dị nnọọ iche na nke ahụkarị mma emulsion polymerization.
Usoro 4: Ntugharị nkwusioru polymerization
polymerization nkwusioru nkwusioru bụ ụzọ dị mma maka mmepụta ụlọ ọrụ nke polymers soluble mmiri mepụtara n'ime afọ 10 na-adịbeghị anya.Di-monie mụrụ polymer nkwusioru nkwusioru AM AM n'iji conductivity, NMR na microscopy eletrọn na 1982.
Usoro 5: Ụzọ polymerization ndị ọzọ
Na mgbakwunye na ụzọ ndị a dị n'elu, enwere ike gbanwee homopolymer na copolymer nke acrylamide na ihe ndị sitere na ya site na mmeghachi omume Mannich na grafting copolymerization.Iwebata amines n'ime polyacrylamide n'oge mmeghachi omume Mannich bụ ụzọ dị mkpa iji nweta cationic polyelectrografting nke polyacrylamide.Amines ndị a na-ejikarị eme ihe bụ dimethylamine, diethylamine, diethanolamine na ndị ọzọ.
A na-anyadokarị AM/AA na starch iji kwadebe resins na-anabata nke ọma, ma ọ bụ ya na monomers macromolecular ndị ọzọ iji nyado AM/AA n'ime ụfọdụ membranes.A na-eji cationic polyacrylamide dị arọ dị elu (CPAM) eme ihe na mmepụta mmanụ, mana HPAM enweghị nnabata nnu adịghị mma.
