Synthesis of Montmorillonite/Acrylic Acid/Acrylamide Tricopolymer and Its Super Absorbent Properties

摘要

Montmorillonite/acrylic acid/acrylamide tricopolymer was synthesized by using aqueous solution polymerization. Some factors affecting the water absorbency of super absorbent composite material, such as the neutralization of acrylic acid, the amount of added montmorillonite, initiator and crosslinking agent were investigated. The best formula for absorbing the running water was proposed, it included 40% montmorillonite, 80% monomer neutralization degree, 0.08% crosslinker amount, andO. 15% initiator, and the water absorbency of the obtained composite materials was 150 times. The FTIR research indicated that montmorillonite was effectively compounded with polymer, it is found that the composite with a good water retention and heat resistance is significant for reducing the product cost and improving the comprehensive property of the composite.
