【Abstract】 One polymer with good property of retained water has been synthesized in this research work. In the presence of dispersing agent, the sys. Methyl acrylate and triethanediol bisacrylate ester was polymerized by suspension polymerization, which was then partially hydrolyzed with alkali. Changing the amount of crosslinking agent and the hydrolysis extent, the amount of retained water of product can vary in the range 300-1000 times. The general amount of contained water can reach to 700-850g/g resin. It was found that the best acceptable supplement of crosslinking agents would be 0.5%. The relations between the water retaining capacities of the polymer and a part of influence factors are also studied.更多还原
