The invention relates to a superabsorbent polymer wherein an increased rate of water absorption is obtained by the addition of an encapsulated blowing agent. The invention relates to a superabsorbent polymer including an encapsulating blowing agent and having a vortex time of 40 seconds or less. In particular, the superabsorbent polymer includes from about 55 to about 99.9 wt. % of polymerizable unsaturated acid group containing monomers from about 0.001 to about 5.0 wt. % of internal crosslinking agent wherein the composition has a degree of neutralization of more than about 20% and from about 0.05 to about 10.0 wt. % of an encapsulated blowing agent.
