Title:
【発明の名称】架橋カルボキシル含有ポリマーの吸水性樹脂粒子と製造方法
Document Type and Number:
Japanese Patent JPH08510484
Kind Code:
A
Abstract:
A water-absorbent resin particle that exhibits a centrifuged absorption capacity of 26 g/g or greater, an absorption under load of 24 g/g or greater at 0.6 psi load. Other aspects of the invention are processes for the preparation of such water-absorbent resin particles which comprise the inclusion of a chlorine or bromine containing oxidizing agent followed by heat-treatment to produce particles with superior centrifuged absorption capacity in combination with high absorption under load at high load, and acceptable levels of residuals. These water-absorbent resin particles provide superior performance when incorporated into absorbent structures.
