Propargyl-PEG5-alcohol（CAS#87450-10-0）

Folasaga

O le propynyl-tetraethylene glycol, e taʻua foi o le polypropynyl alcohol, o se polymer o loʻo i ai vaega faʻaogaina propynyl. O lo'o ta'ua i lalo se fa'atomuaga i meatotino, fa'aoga, metotia sauniuni ma fa'amatalaga saogalemu ole propynyl-tetrameric glycol:

Tulaga lelei:

- O le propynyl-tetraethylene glycol ose vai e le lanu samasama pe malo.

- E lelei le solubility ma soluble i le tele o solu fa'aola ma vai.

Fa'aaogā:

- E mafai ona faʻaaogaina e avea o se polymer modifier, viscosity modifier, impregnation agent ma mafiafia, ma isi.

Metotia:

- Proynyl-tetraethylene glycol e mafai ona faʻapipiʻiina i se laasaga e lua, lea e muamua faʻafeiloaʻi ai vaega faʻatino propynyl i totonu o le filifili polyethylene glycol e faʻaaoga ai le propynylating agent, sosoo ai ma le polymerization.

- Polymerization tali e masani lava ona fa'aosoina e fa'amamafa u'amea pei o siliva po'o masima platinum.

Fa'amatalaga Saogalemu:

- Propynyl-tetraethylene glycol e mu ma e tatau ona aloese mai le faʻafesoʻotaʻi ma afi mumu poʻo mea vevela maualuga.

- Fa'aaoga totigilima ma mata talafeagai e 'alofia ai le pa'i ma le manava pe a fa'agaioi.

- E tatau ona teu i totonu o se nofoaga malulu, lelei le savili ma mamao ese mai mea faʻamaʻi.

- Pe a faʻaaogaina ma faʻaaogaina le propynyl-tetrameric glycol, e tatau ona mataʻituina faiga saogalemu ma tulafono faatonutonu talafeagai.
