摘要:
Cross-linked esters of hyaluronic acid are provided which result from the esterification of polyhydric alcohols with two or more carboxy groups of the hyaluronic acid polysaccharide. These cross-linked esters are useful in the field of biodegradable plastics for sanitary and surgical articles and in the pharmaceutical and cosmetic fields for the preparation of useful compositions and articles.
