- •
The over-crosslinking is occurred between C
O bond in COO− of HPAM and Cr3+.- •
The Ca2+ reacts with the C
O bond in COO− of HPAM.- •
The syneresis water originates from the water bounded to carboxylate group of HPAM.
- •
Syneresis inhibitor restrains the generation of the Cr3+ polynuclear olation complex.
