  • Process for manufacturing a thermoformable plasticized composite containing cellulose fiber and a moldable polymer
    Patent number: 9809687
    Abstract: The present invention concerns a process for manufacturing a thermoformable plasticized composite containing cellulose fiber and polylactide by blending the dry cellulose fiber and a compatibilizer in a compactor into pellets, and subsequently reacting the reactive compatibilizer and the mixture of cellulose fiber and polylactide by compounding. The invention also concerns a composite manufactured using said process, as well as further processed products.

  • METHOD FOR THE MANUFACTURE OF OLIGO- AND POLYESTERS FROM A MIXTURE OF CARBOXYLIC ACID OBTAINED FROM SUBERIN AND/OR CUTIN AND USE THEREOF
    Publication number: 20110319504
    Abstract: 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 mono-, 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.
