The structure-properties relationships of sustainable materials derived from biomass-based monomers are investigated, focusing on hybrid styrene/terpene-based copolymers with blocky microstructures, such as β-myrcene– and β-ocimene–styrene copolymers. The samples show complex glass transition dynamics, as evidenced by the physical aging experienced by the amorphous phase in styrene-rich copolymers. The tendency of styrene- and terpene-rich sequences to give heterogeneous morphologies with correlation strength extending over 10–40 nm is outlined, through small-angle X-ray scattering analysis. A new class of terpene-based hybrid systems, holding promise for applications in surface coating technologies, is identified.

Abstract
The structure-properties relationships of sustainable materials derived from biomass-based monomers are investigated, focusing on hybrid styrene/terpene-based copolymers with blocky microstructures, such as β-myrcene– and β-ocimene–styrene copolymers. The samples show complex glass transition dynamics, as evidenced by the physical aging experienced by the amorphous phase in styrene-rich copolymers. The tendency of styrene- and terpene-rich sequences to give heterogeneous morphologies with correlation strength extending over 10–40 nm is outlined, through small-angle X-ray scattering analysis. A new class of terpene-based hybrid systems, holding promise for applications in surface coating technologies, is identified.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
