4. Apparatuses & Reagents
1) Apparatuses
500㎖ erlenmeyer flask
Separate funnel
Vacuum evaporator
Vacuum flask
Buchner funnel
Aspirator
Water bath
Pipette
Filter paper
Beaker
5. Procedure
① purification of MMA
② NaOH 5% add to MMA, remove the bottom part then add CaCl2 to remove the water
---------
① 200㎖ Distilled water into 300ml erlenmeyer flask
② 2.0g cellulose, 8.2g ceric ammonium nitrate (Ce(NO3)4․2NH4NO3)
③ 5㎖ MMA(purified) into the did beaker water bath(29℃) for 1h and add hydroquinone 2㎖
④ use the buchner funnel to filter and then dry, weight
⑤ add some THF and filter again dry weight again

6. Result
⑴ weight of MMA : ( MMA sp.= 0.942g/cm)
⑵ weight of filter paper : 0.8777 g
⑶ weight of grafted PMMA and ungrafted PMMA : (8.5234 - 0.8777) = 7.6457 g
⑷ weight of grafted PMMA : (5.3548 - 0.8777) = 4.4771 g
⑸ yield
