| titleOfInvention | Process for preparing hydrogel |
| abstract | 1. Process for the preparation of a three-dimensional structure, characterized in that it consists in forming an acid aqueous solution of a natural, non-crystalline protein polymer of animal or plant origin, or of a mixture of such polymers, these polymers having low molecular weights of not more than 100 000, in heating the solution to a temperature between 55 and 65 degrees C, in adjusting the pH of the solution to between 3.5 and 5.5, in adding a crosslinking agent to the solution and incorporating it therein, in a ratio of 0.5 % to 15 % by weight, the temperature of the solution being kept at between 55 and 65 degrees C, in drying the solution until its moisture content does not exceed 10 % at a maximum temperature of 35 degrees C or an equivalent temperature in vacuo, so as to form a crosslinked polymeric structure, in subjecting this structure to thorough washing with water, in subjecting the structure washed in this way to dehydration by immersion in a water-miscible organic solvent, in subjecting the structure to thorough washing with water, and in drying the structure again at a maximum temperature of 35 degrees C, until its moisture content does not exceed 10 %. |
