Figure 1
Structures of various polymeric precipitants. (a) M-type Jeffamines. R1 = —H for EO or —CH3 for PO. The PO/EO molar ratio is 29/6 for Jeffamine M2005, 10/31 for Jeffamine M2070 and 9/1 for Jeffamine M600. (b) Pentaerythritol ethoxylate. (c) Pentaerythritol propoxylate. (d) Polyvinyl pyrrolidone. (e) Polypropylene glycol. (f) Polyvinyl alcohol. (g) Polyacrylate. (h) Cellulose-based polymers. R1 = —H, —CH3 or —CH2CHOHCH3 (hydroxypropyl methylcellulose), —H or CH2CO2H (carboxymethyl cellulose). (i) Poly(ethylene imine). (j) Di[poly(ethyleneglycol)] adipate. (k) Jeffamine ED2003. (l) Jeffamine D2000. (m) Jeffamine SD2001. (n) T-type Jeffamines. (o) Polyacryl amide. (p) Glycerol ethoxylate. (q) Acrylic acid/maleic acid copolymer. (r) Vinylpyrrolidone/vinylimidazole copolymer. |
