摘要

This study presents an innovative approach to synthesize bio-based polydiene polymers from citronellall by converting it into the diene monomer 6

10-dimethyl-1

9-undecatriene (DMUT) via Wittig reaction

followed by neodymium-catalyzed polymerization.

Abstract

As a naturally occurring terpenoid that is abundant in essential oils

citronellal remains largely unexplored in polymer science. Herein

we present a novel strategy for converting bio-based citronellal into the diene monomer 6

10-dimethyl-1

9-undecatriene (DMUT)

which undergoes neodymium-catalyzed coordination polymerization to yield poly(6

10-dimethyl-1

9-undecatriene) (PDMUT)

a bio-derived polydiene polymer. This provides a facile and sustainable route for transforming renewable citronellal into functional polymers. The effects of polymerization conditions on the catalytic performance and polymer characteristics

including molecular weight

polydispersity

and microstructure

were systematically investigated. In addition

DMUT was successfully copolymerized with isoprene (IP) and 1

3-butadiene (BD)

yielding copolymers with tunable compositions and microstructures. These results demonstrate the versatility of DMUT as a renewable building block for both homopolymers and copolymers

paving the way toward bio-based elastomeric materials with customizable properties.
