  • Publication number: 20150283284
    Abstract: The present invention relates to a particulate superabsorbent polymer composition having fast absorption and a method of making the particulate superabsorbent polymer comprising a monomer solution comprising a foaming agent and a mixture of a lipophile surfactant and a polyethoxylated hydrophilic surfactant wherein the particulate superabsorbent polymer composition has a mean particle size distribution of from 300 to 500 ?m and a vortex time of 30 to 60 seconds. The present invention further includes particulate superabsorbent polymer compositions surface treated with other components. The present invention further includes absorbent cores and articles including the particulate superabsorbent polymer compositions.

  • Patent number: 5555411
    Abstract: Method and means are described which provide a way for an application program to be generated to include dependent control blocks which indicate which support programs must be initialized in the run-time support environment prior to the application program's initialization and which must be terminated after its termination. Since support programs may be dependent on each other, a topological sort is performed to determine an order in which the support programs can be initialized so that no routine is initialized before all of its prerequisites are initialized. The initialization order is saved, so that following the execution of the program, termination can be performed in the reverse order.
