Talosaga Oloa
Faʻaaogaina i le gaosiga o paʻu, palasitika, ma polymers.
a) Gaosiga o: polystyrene fa'alauteleina (EPS);
e) Gaosiga o le polystyrene (HIPS) ma le GPPS;
i) Tuuina atu o styrenic co-polymers;
o) Gaosiga o resini polyester e le'o tumu;
u) Tuuina atu o pa'u styrene-butadiene;
f) Tuuina atu o le styrene-butadiene latex;
g) Gaosiga o styrene isoprene co-polymers;
h) Gaosiga o fa'ata'apeina polymeric fa'avae styrene;
i) Gaosiga o polyol fa'atumu.E masani ona faʻaaogaina le Styrene e fai ma monomer mo le gaosiga o polymers (pei o le polystyrene, poʻo nisi paʻu ma latex)
Styrene maleic anhydride (SMA po'o SMAnh) o se polymer synthetic lea e fausia i luga ole styrene ma maleic anhydride monomers.Ole monomers e mafai ona toe fa'asolo lelei, ma avea ai ma sui kopolimer,[1] ae (fa'afuase'i) fa'akopolymerization e itiiti ifo i le 50% maleic anhydride anotusi e mafai fo'i.O le polymer e fausia e se polymerization radical, e faʻaaoga ai se organic peroxide e fai ma amataga.O uiga autu o le SMA copolymer o lona foliga manino, maualuga le vevela, faʻamautu maualuga, ma le gaioiga faʻapitoa o vaega anhydride.O le vaega mulimuli e maua ai le solubility o le SMA i alkaline (vai-faavae) fofo ma faʻasalalau.
O lo'o maua le SMA i le lautele o le mamafa mole mole ma maleic anhydride (MA) anotusi.I se tuʻufaʻatasiga masani o na meatotino e lua, o loʻo avanoa le SMA e pei o se tioata manino tioata e mafai ona faʻaaogaina i le tele o ituaiga o talosaga.SMA polymers ma le mamafa molecular maualuga e masani ona faʻaaogaina i faʻainisinia palasitika talosaga, e masani lava i le aʻafiaga faʻaleleia ma filifili tioata faʻatumu fesuiaiga.I le isi itu, e faʻaaogaina le SMA e faʻaaoga ai lona manino faʻatasi ma isi mea manino e pei o le PMMA poʻo le vevela vevela i le vevela-faʻateleina isi mea polymers pei ole ABS poʻo le PVC.O le solubility o le SMA i vaifofo alkaline e talafeagai mo le tele o talosaga i le fanua o sizings (pepa), binders, dispersants ma coatings.Ole fa'agaioiga fa'apitoa ole SMA e avea ai ma sui talafeagai mo le fa'afetauiina o polymers masani e le fetaui (fa'ata'ita'iga ABS/PA fa'afefiloi) po'o feso'ota'iga.O le vevela suiga tioata o Styrene maleic anhydride e 130 – 160 °C.
