Document Type and Number:
Japanese Patent JPH06506252
Kind Code:
A
Abstract:
The subject invention pertains to large particle size, attrition-resistant, continuous, but wrinkled, high surface area aqueous fluid absorbent polymers, preferably of a crosslinked acrylic acid or acrylate. These absorbents have absorption rates superior to spherical absorbents. The subject invention further pertains to a process of preparing such polymers comprising suspension polymerization with an at least partially oil phase soluble initiator. The subject invention further pertains to absorbent structures containing such polymers, and to the use of such polymers therein.
