- METHOD FOR THE MANUFACTURE OF OLIGO- AND POLYESTERS FROM A MIXTURE OF CARBOXYLIC ACIDS OBTAINED FROM SUBERIN AND/OR CUTIN AND THE USE THEREOF
-
The invention relates to a method for processing mixtures of carboxylic acids obtained as hydrolysis products of suberin and cutin, particularly suberin and cutin isolated from birch bark, to give oligo- and polyesters, or corresponding ester-ethers, as well as the use of the products thus obtained as lubricants, fuel components, plasticizers, surface active agents, environmentally friendly agents for modifying wood, binders in coatings, adhesives, printing inks and composites, further in various cosmetic applications.
