摘要:
A liquid-absorbing material composition containing a crosslinking agent (component A), N-vinylcarboxamide copolymer (component B) having a functional group capable of crosslinking with the component A, water (component C), a water-soluble organic solvent (component D) and a plasticizer (component E), a molded liquid-absorbing material prepared from the composition, a method of manufacturing the molded liquid-absorbing material, and uses thereof are provided. The liquid-absorbing material composition has a high flowability, and gives a uniform continuous layer so that it can be directly molded readily into film- or sheet-shaped molded liquid-absorbing material without requiring secondary processing as in the case of conventional water-absorbing polymer. Use of the liquid-absorbing material composition allows manufacture in short time of molded products which are excellent in liquid-absorbing performance that can be utilized as a freshness retaining agent, a moisture-conditioning agent, an agricultural and horticultural water-retaining sheet, a soil improving agent, an anti-dewing agent, sanitary goods, a waste liquid solidifying material, a water preventing sheet, a water running preventing shielding material, a pharmaceutical, a medical tool, a humectant or desiccant.
摘要:
A collagen powder is obtained by wet-pulverizing a purified animal tissue consisting mainly of collagen in water at a collagen concentration of 1-30% by weight at a water temperature of not more than 37.degree. C. and a pH value of 2-8, tanning treating the pulverized tissue at a pH level of 2-7 with a polyvalent metal tanning agent to obtain a stabilized wet collagen product, dehydrating the wet collagen product at a pH level of 4-8, and then drying and pulverizing the dehydrated product into a powder. This powder can be used as an additive for modifying paints, artificial leathers, molding materials and the like based on synthetic resins such as thermoplastic resins. The materials obtained with this powder have an excellent appearance, feel, and moisture-absorbing and moisture-releasing properties.

Disclosed is a collagen powder having a good dispersion stability, in which the content of particles having a particle size smaller than 40 .mu.m is at least 85% by weight, the water absorption is 120 to 300%, and the apparent bulk density is 0.10 to 0.30 g/cc. This collagen powder is advantageously used for a leather-like surface layer-forming agent and a leather-like molded article.
