Aqueous cationic polymerization of β-myrcene, a naturally occurring monomer, was performed for the first time using a water-dispersible Lewis acid surfactant combined catalyst (LASC) prepared from ytterbium chloride and a branched sodium dodecylbenzenesulfonate surfactant. At 40 °C, poly(β-myrcene)s of high molecular weight (M n up to 150 kg mol −1 ) and low glass transition temperature (T g < −63 °C) were obtained. They possess predominantly 1,4-units (∼43[%] cis and ∼50[%] trans) and few 3,4-units (∼7[%]) together with both regular head-to-tail (62-72[%]) and inverse (5-10[%] head-to-head and 23-28[%] tail-to-tail) sequences. The LASC showed also high efficiency in catalyzing the emulsion cationic copolymerization of β-myrcene and styrene, affording the synthesis of random copolymers with high molecular weights (M n from 60 to 120 kg mol −1 ) and single glass transition temperatures (T g 's from −43 to 15 °C). Finally, a simple procedure was developed to recover the catalyst from the reaction
