Abstract
Kopolimer NIPAM-co-DMAAPS yang terdiri dari
monomer N-isopropylacrylamide (NIPAM) dan N,N’-
dimethyl(acrylamidopropyl)ammonium propane sulfonate
(DMAAPS) akan disintesa kemudian dikarakterisasi. Hal ini
dilakukan untuk mendukung penelitian sebelumnya yang fokus pada penyelidikan mengenai kemampuan adsorpsi dan desorpsi NIPAM-co-DMAAPS gel. DMAAPS bersifat thermosensitive dan zwitterionic. Zwitterion ini memiliki dua muatan sekaligus yaitu positif dan negatif yang dapat digunakan untuk menyerap kation dan anion secara simultan. Sedangkan NIPAM bersifat thermosensitive digunakan sebagai spacer untuk menghindari ikatan inter chain, intra chain, dan intra group antar grup bermuatan pada homopolimer zwitterion poly(DMAAPS). Penelitian ini bertujuan untuk mengetahui pengaruh rasio
konsentrasi monomer pada kopolimer NIPAM-co-DMAAPS
terhadap viskositas kopolimer, sifat ketertarikan air kopolimer, sifat fasa transisi termosensitif kopolimer dalam larutan Zn(NO3)2, pengaruh suhu transisi terhadap daya adsorpsi ion Zn2+ kopolimer NIPAM-co-DMAAPS serta mempelajari korelasi antara viskositas, sifat fasa transisi thermosensitive kopolimer poly[NIPAM-co-DMAAPS] dalam larutan Zn(NO3)2. Kopolimer NIPAM-co-DMAAPS disiapkan melalui reaksi polimerisasi radikal bebas dengan menggunakan N,N,N’,N’-
tetramethylethylenediamine (TEMED) sebagai akselerator,
ammoniumperoxodisulfate (APS) sebagai inisiator dengan
variasi konsentrasi monomer NIPAM:DMAAPS yaitu 9:1, 8:2
dan 7:3. Semakin tinggi rasio konsentrasi monomer NIPAM pada kopolimer NIPAM-co-DMAAPS, viskositas kopolimer akan
semakin tinggi. Semakin tinggi suhu transisi maka jumlah ion yang teradsorp cenderung menurun. Pada rasio konsentrasi monomer 9:1, sifat fasa transisi dalam larutan Zn(NO3)2 sebesar 56 °C.

Copolymer NIPAM-co-DMAAPS, consists of monomers
N-isopropylacrylamide (NIPAM) and N,Ndimethyl(acrylamidopropyl) ammonium propane sulfonate
(DMAAPS), will be synthesized and characterized. It is to
support previous research focusing on investigations on the
adsorption and desorption capacity of NIPAM-co-DMAAPS gel.
DMAAPS is thermosensitive and zwitterionic. Zwitterion has two
charges in the same time i.e. positive and negative that can be
used to adsorp cation and anion, simultaneously. While NIPAM,
which thermosensitive, is use as spacer to avoid inter-chain, intrachain, and intra-group between charged groups on the zwitterion
homopolymer poly(DMAAPS). This study aims to determine the
effect of monomer concentration ratio on NIPAM-co-DMAAPS
copolymers on copolymer viscosity, water properties of
copolymer, transitional thermosensitive transition phase (UCST
and LCST) copolymer in Zn(NO3)2 solution, transition
temperature influence on adsorption ability of Zn2+ ions NIPAMco-DMAAPS copolymer and study the correlation between
viscosity, thermosensitive transition phase of poly (NIPAM-coDr. Eva Oktavia Ningrum, S.T., M.S.

DMAAPS) copolymer in Zn(NO3)2 solution. Zn(NO3)2 is employ
as the interaction media between the copolymer and ions.
Copolymer NIPAM-co-DMAAPS will be prepared by free radical
polymerization with N,N,N’,N’-tetramethylenediamine (TEMED)
as the accelerator, ammonium peroxodisulfate (APS) as the
initiator and the variation of monomer concentration
NIPAM:DMAAPS i.e. 9:1, 8:2, and 7:3. The higher the ratio of
NIPAM monomer concentration to NIPAM-co-DMAAPS
copolymer, the higher the copolymer viscosity. The higher the
transition temperature the amount of adsorbed ions tends to
decrease. At a monomer ratio of 9: 1, the transition phase
properties in Zn(NO3)2 solution were 56 °C.
