Description

General description

Methyl 10-undecenoate is the chain stopper in the polymerization of long-chain aliphatic α,ω-diene through acyclic diene metathesis (ADMET). This helps in tuning the molecular weight of the resulting polyester in a range varying from 10 to 45 kDa.

Application

Methyl 10-undecenoate is an unsaturated fatty acid ester that can be used as a substrate:

• To prepare bifunctional polymer precursors via hydroformylation reaction.
• To synthesize α,ω-ester amides via aminocarbonylation in the presence of palladium catalyst.
• To modify commercial silicone monomer, 1,3,5,7-tetramethylcyclotetrasiloxane, for the preparation of silicone hollow nano/microstructures in water by hydrosilylation reaction.
