Iimveliso

Imveliso inokuqalisa ngokufanelekileyo i-polymerization kwiqondo lokushisa eliphantsi kunye noxinzelelo oluphantsi ukuvelisa i-polymer ephezulu kunye ne-molecular weight.

Umqalisi weVa-044 unobuchule obuphezulu bokuqalisa, ubunzima obuphezulu bemolekyuli, ukunyibilika kakuhle kwamanzi kunye nentsalela encinci.

I-VA-044 initiator ifunyenwe ngokuzisa amaqela e-hydrophilic kwi-molecule ye-azonitrile initiators, kwaye ine-solubility efanelekileyo yamanzi.Ke ngoko, i-VA-044 initiator ifanelekile ngokubanzi kwi-polymerization yesisombululo samanzi kunye ne-emulsion polymerization ye-polymer synthesis.Xa kuthelekiswa neendidi ngokubanzi zabaqalisi be-azo, umqalisi we-VA-044 unobuchule obuphezulu bokuqalisa, ubunzima obuphezulu bemolekyuli, ukunyibilika kakuhle kwamanzi, kunye nomzimba omncinci oshiyekileyo.Xa kuthelekiswa ne-inorganic persulfate kunye nabanye abaqalisi be-soluble water-soluble, i-VA-044 initiator inokuqhuba i-reaction decomposition egudileyo, ezinzileyo kwaye elawulwayo ukuvelisa umgca ophezulu kunye neepolymers eziphezulu ze-molecular weight.

Ngokungafani neemveliso ze-azo nitrile, kuba ayinayo amaqela e-cyano, iimveliso zokubola ze-VA-044 zokuqalisa azikho inetyhefu.Ngelo xesha, ibola ngokuthe ngcembe kunabanye abaqalisi, inezinga eliphezulu lokuguqulwa, kwaye akukho ntsalela okanye i-agglomeration eyenzekayo ngexesha lenkqubo ye-polymerization.Iyakwazi ukuqalisa ngokufanelekileyo i-polymerization kwiqondo lokushisa eliphantsi kunye nokugxininiswa okuphantsi ukuvelisa umgca ophezulu kunye neepolymers eziphezulu ze-molecular weight.Ngoko ke, i-VA-044 initiator isetyenziswa ngokubanzi kwi-polymerization yesisombululo esimanzi kunye ne-emulsion polymerization ye-polymer synthesis, njenge-monomer acrylamide polymerization, i-Initiator ye-polymerization reactions ezifana ne-styrene emulsion polymerization kunye ne-monomerization ye-styrene kunye ne-butyl acrylate.
