    Abstract: A water absorbent agent having a high water absorption multiplying factor where stickiness after absorbing liquid can be reduced when used as a hygienic material is produce by a method for manufacturing the water absorbing agent. The method for manufacturing a water absorbent agent having a centrifuge retention capacity (CRC) of 30 g/g or greater, includes subjecting an aqueous solution of a monomer that includes an acrylic acid (salt) to a polymerization step, a drying step, and a surface cross-linking step, and a step for adding α-hydroxycarboxylic acid (salt) before the drying step. The atomic weight of the soluble portion eluted when the water absorbent agent absorbs liquid and swells can be reduced by the α-hydroxycarboxylic acid (salt) before the drying step to reduce the stickiness of the water absorbent agent after absorption of liquid, which leads to discomfort during use of disposable diapers and the like.

    Abstract: Liquid crystal polymers (LCPs) are described herein that include novel arrangements of bio-mimicking properties for use in surgery, therapy, and treatment of medical or comfort issues. Through the particular arrangements medical devices and portions of them may be adapted to have properties that dampen and dissipate vibrations such as shocks to body tissues during surgical recovery and/or during subsequent use. This dampening is attained by novel arrangements of LCP and processes for forming them that vary from prior attempts at synthesizing activated LCP elements. These novel arrangements include using LCP bodies that include thicknesses and properties that have not been demonstrated or achieved for medical or other purposes and that are achieved using distinct processes. These novel LCP arrangements and methods of creating them can produce medical devices that bio-mimic natural tissue or operation to provide better results for patients.
