Isicelo

1. Ukusetyenziswa kwiimpendulo ze-polymerization

I-4,4'-azobis (4-cyanopentanol) yi-azo compound enokusetyenziswa njenge-initiator ye-polymerization reactions. Kwinkqubo ye-polymerization yamahhala, inokubola ukuvelisa i-radicals yamahhala ukuqalisa i-polymerization ye-monomer. Ngokomzekelo, kwi-polymerization reaction ye-vinyl monomers ezifana ne-acrylates kunye ne-styrenes, inokulawula ngokufanelekileyo ukuqaliswa kunye nesantya se-polymerization reaction. I-radicals yamahhala eveliswa ngokubola kwayo inokuqalisa ukuvulwa kweebhondi eziphindwe kabini kwiimolekyuli ze-monomer, kwaye emva koko zidibanise omnye komnye ukuze zenze amakhonkco e-polymer.

Lo mqalisi uneengenelo ezithile, ezinjengokubonelela ngesantya esizinzileyo sokwenziwa kweradical free ngokwentelekiso phantsi kweemeko ezifanelekileyo zobushushu, ukuze i-polymerization reaction ikwazi ukuqhubeka kakuhle, nto leyo enceda ekudityanisweni kweepolymers ezinobunzima obumxinwa bemolekyuli.

2. Indima ekulungiseleleni izinto ezinogwebu

Isenokusetyenziswa nasekulungiseleleni izinto ezinogwebu. Ekulungiseleleni izinto ezinogwebu ezifana ne-polyurethane, i-4,4'-azobis (4-cyanopentanol) inokuthatha inxaxheba ekuphenduleni ukuvelisa igesi, kunye ne-radicals yamahhala kunye namanye amaqela asebenzayo avelisiweyo ngokubola kwawo nawo afaka isandla kwi-crosslinking kunye nokunyangwa kwe-polymer matrices njenge-polyurethane. Esi siphumo simbini senza ukuba izinto ezinogwebu zenze isakhiwo se-pore esifanayo, kwaye ubungakanani kunye nokuhanjiswa kwee-pores kunokulawulwa ngokulungelelanisa iimeko ezifana ne-dosage yazo, ngaloo ndlela kuphuculwe iipropati ezibonakalayo zezinto ezinogwebu, ezifana nokunciphisa ubuninzi bezinto eziphathekayo, ukuphucula ukunyameka kwezinto kunye neempawu zokunciphisa, njl.
