“…Ac orresponding procedure has also been described for polysiloxane with 14 as ap endent group (Scheme19), resulting in ap olymer with the ability to form smecticphases. [125] In this context, interesting chitosan-abietic acid conjugates have been synthesized and investigated in terms of their drugreleaseb ehavior. [126] Similarly,c hloro-substituted 17 is another important building block, which is often used for attachment onto polymer backbones that contain OH andN Hgroups.…”

The functionalization and polymerization of biobased monocyclic terpenes and their derivatives for the synthesis of sustainable polymers is described, especially in view of the synthetic routes and properties of the obtained macromolecular architectures. Comparison of these procedures and the obtained materials with "classical" oil-based approaches, and also with alternative biobased routes, gives interesting insights into the potential of these small terpene building-block structures for modern polymer science and technology.

“…The role of the two parts in the hydrosilylation can be reversed, namely, the Si-H group can be introduced to Chol and C¼C to polysiloxane (as pendant groups) [168], where the impact of polysiloxanes structure (linear and branched) on the properties of the conjugates is also revealed. Apart from Chol and menthol, polysiloxane with geraniol pendant groups has been made via a similar strategy, and a smectic A phase observed for the polymer conjugate [169].…”

Terpenes or terpenoids are a large class of diverse biological compounds derived from isoprene. Due to their abundance in nature and desirable properties, there has been great interest in producing polymers with terpenes as either functional entities or as the main constituent. Terpene-based polymers have found applications as biomedical or liquid crystalline materials and, more importantly, have greatly contributed to the concept of sustainable polymer chemistry. The design and preparation of terpene-based polymers have involved different chemical strategies and a wide variety of polymerization techniques, making use of the chemical functionalities in terpene molecules, e.g. (conjugated) double bonds, hydroxyl and carboxyl groups. This review describes the synthetic methodologies for terpene-based polymers, classified by the position of terpene entities in the polymer chains, i.e., main chain, terminal or central group, and pendant group.

Bioconjugate amphiphiles comprising triterpene and poly(ethylene oxide) (PEO) were studied according to their thermoresponsive aggregation behavior (LCST) in water. Cholesteryl-PEO (CE) and betulinyl-PEO (BE) comprising <70 wt% PEO precipitated from water upon heating. CE, but not BE, solutions contained nanoscopic aggregates at room temperature causing different thermoprecipitation behaviors. Solutions containing 5 wt% solutions of BE with short PEO chains demonstrated dual thermoresponsive behavior, precipitating at high temperature and forming hydrogel at low temperature. A BE multiblock copolymer was found to form large aggregates, presumably vesicles, in water. Results suggest that the solution properties of triterpene-PEO amphiphiles can be controlled by the chemical composition and structure.
