Polyamides are very important polymers, with applications from commodities up to high-performance materials for, for example, fibers or for the biomedical sector. Nowadays, still most of them are synthesized from fossil resources. With regards to sustainability and bioeconomy, and especially regarding the new structures and properties that can thus be achieved, the preparation of polyamides (PAs) from natural precursors is getting more and more important. For this, especially the utilization of terpenes, a large and important group of natural products with different functions in nature (regulators, defense signals, etc.), is important, which is described herein. Similar approaches are interesting from a scientific point of view regarding, for example, structure-function-relations, but also with regards to different applications as, for example, high-performance or biomedical materials. Practical applications: Terpene-based polyamides can find many applications, from commodities up to high-performance fibers and special materials in (bio)medicine, for example, drug delivery, tissue engineering, etc.

Motivated by increasing attention to biobased and potentially sustainable polymers from renewable sources, this work describes the synthesis and anionic ring-opening polymerization (AROP) of the terpenoid-derived farnesyl glycidyl ether (FarGE) as a hydrophobic epoxide building block for the synthesis of biobased, amphiphilic polyethers that represent novel, nonionic surfactants. In combination with ethylene oxide (EO), the synthetic strategies employed provide access to both amphiphilic diblock (mPEG 114 -b-PFarGE m ) and statistical copolymers (PEG nco-PFarGE m ), featuring facile tunability of their amphiphilic and surfactant properties. The versatile application of FarGE for different polyether architectures is demonstrated by the wellcontrolled molecular weights in the range of 5040−11170 g mol −1 and narrow molecular weight distributions (Đ = 1.04−1.11), both for block and statistical architectures. Owing to the unexpected, nearly ideally random microstructure of the statistical EO/FarGE copolyethers, determined by in situ kinetics (r EO = 1.18 and r FarGE = 0.85), the branched alkenyl side chain impedes the crystallization of polyethylene glycol (PEG) with increasing FarGE incorporation, allowing for fine-tuning of polymer properties. Observing a low glass transition temperature (T g ) of around −70 °C for the PFarGE homopolymer, the thermal analysis also unveils farnesyl side-chain control of the T g even at low FarGE content (7.6 mol %). Detailed investigations of aqueous polymer solutions reveal self-assembly of the amphiphilic copolymers into micelles and aggregates, characterized by very low critical micelle concentrations (CMC, 10−53 mg L −1 ), as well as larger clusters (R H,micelle = 17−35 nm and R H,cluster = 59−107 nm). The results demonstrate the enormous potential of terpenes and terpenoids for partially biobased surfactant alternatives.
