Abstract

PURPOSE: To obtain a tubular water-absorbable high polymer which has a moderate softness in water with a mechanical strength by performing a dipping forming of a mixed concentrated liquid of a polyvinyl alcohol aqueous solution and a polyacrylate aqueous solution to gelatilize it by esterification.
CONSTITUTION: A mixed concentrated liquid of polyvinyl alcohol and polyacrylate is made at a larger rate in wt.% for the former than the latter and a concentrated liquid of the former alone undergoes a dipping molding using a proper core, and further, a heat processing for more than two hours under an air temperature of about 100°C-110°C to esterify. A tubular gel thus obtained becomes a material having a softness, elasticity and a mechanical strength similar to soft rubber in a state of swelling in water. The tubular gel has a shear strength more than 5-100 times as much as the conventional membrane-like gel. When it contains polyacrylate, the gel provides a characteristic as mechanochemical actuator. Being a water absorbing polymer, the gel has a characteristic of absorbing and swelling from a dry condition and also of transmitting various ions in water and an aqueous solution between the inside and outside of the gel membrane, thereby achieving a higher mechanical strength.
