摘要： The intention was to provide a substantially biodegradable pressure-sensitive adhesive being to a large extent based on materials of biological origin which combines sustainability features with good tack and good adhesion properties on a variety of substrates.
This was accomplished by a pressure-sensitive adhesive comprising
a polyhydroxyalkanoate, characterized in that the polyhydroxyalkanoate features 1 to 20 weight-% of structural units having a side chain functionalization moiety comprising at least 10 C-atoms.
