Green chemistry" has attracted increased interest from various sectors of industry [1-3]. One of its underlying principles is the use of renewable resources, e.g. for monomer synthesis and polymer modification, to save fossil resources, such as coal, oil, and gas, because nature produces a wide variety and high quantities of both small molecules and polymers [4-6]. Though natural polymers have been used by humans for thousands of years, the combination of small molecules obtained from renewable resources with modern reactions developed by chemists to introduce polymerisable functional groups extends the application potential even for small molecules. The resultant bio-based monomers ...
