【発明の名称】架橋ポリアスパルテートからなる吸収ゲル化物質
Document Type and Number:
Japanese Patent JP2000510502
Kind Code:
A
Abstract:
Absorbent gelling materials are prepared by crosslinking polyaspartate units. The crosslinked homopolymers exhibit improved gel volumes, gel strengths and extractable material characteristics. Using diamine crosslinkers in an amount of 2.5-30 percent by weight, the blue-dextran saline gel volumes of at least 15 can be obtained. Similarly, gel strengths of 300 N/m2 or better, including gel strengths above 3000 N/m2, can be obtained. The resulting product is susceptible of a variety of uses, is biodegradable, and can be prepared in a particle size suitable for use in a diaper.
