Abstract
(DE)
Biologisch abbaubarer Werkstoff auf der Basis von Schellack, wobei dieser erhältlich ist, indem Schellack oder ein Schellackderivat, mindestens eine C6-C10-Carbonsäure und mindestens eine Dicarbonsäure unter Säurekatalyse miteinander zur Reaktion gebracht werden.
(EN)
The proposed biologically degradable material is based on shellac and can be obtained by causing shellac or a derivative thereof to react with at least one C6-C10 carboxylic acid and at least one dicarboxylic acid using acid catalysis.
(FR)
L'invention concerne un matériau biodégradable à base de gomme-laque, que l'on obtient en faisant réagir, par catalyse acide, la gomme-laque ou un dérivé de gomme-laque avec au moins un acide carboxylique C6-C10 et avec au moins un acide dicarboxylique.
