APEG (0.006 mol) was added in a three-necked flask, using moderate amount of water to dissolve in a heated water bath.
In laboratory studies, the best parameters of copolymer SJ-1 were obtained: monomer concentration was 15wt%; molar ratio of n(AM): n(AMPS): n(APEG) was 14:5:1; the reaction temperature was 60[degrees]C; the concentration of monomer initiator was 0.2 wt%.
In Australia, BelAZ recently appointed APEG as its distribution and support partner.
"We see this as a big development for the Australian resources sector," said APEG Director Shane Halliwell.
Structures of PA, APEG, APEL, and POLY (MA--APEL--PA) were also explored by a Bruker NMR analyzer (AVANCE AV-500, Bruker, Switzerland) operating at 500 MHz.
The FTIR spectra of APEG, APEL, and POLY(MA-APEL-PA) are exhibited in Fig.
We developed a simple source apportionment method for [PM.sub.10] using the latest data available from APEG
