PCT No. PCT/FR90/00253 Sec. 371 Date Oct. 7, 1991 Sec. 102(e) Date Oct. 7, 1991 PCT Filed Apr. 10, 1990 PCT Pub. No. WO90/12055 PCT Pub. Date Oct. 18, 1990.The invention relates to a process of cross-linking collagen. This process is of the type comprising the formation of amide bonds by means of acylazide groups and is characterized in that the collagen is reacted with diphenylphosphorylazide. The process according to the invention makes it possible to simplify the collagen cross-linking process and to adjust the degree of cross-linking at discretion without introducing any cross-linking agent.
