| dc.description | The monomer β-myrcene, a renewable resource, was polymerized in cyclohexane using two different Ziegler-Natta catalyst systems based on neodymium Nd(Oi-Pr)3 and NdV3. The Nd(Oi-Pr)3 was combined with [HNMe2Ph][B(C6F5)4] (or [CPh3][B(C6F5)4]) and Al(i-Bu)3 (or Al(i-Bu)2H). Next, the NdV3 was activated using Al(i-Bu)3 and AlEt2Cl. Both catalyst systems exhibited high polymer yields near 100 % in the established reaction time, high polymer molecular masses, and broad molecular mass distributions. The catalyst systems gave an effective and stereospecific polymerization reaction of β-myrcene providing high cis selectivity of 1,4-polymyrcenes (> 92 %) with a glass transition temperature between −66 and −62 °C. The above-mentioned features of resulting elastomers in conjunction with the polymer's molecular masses and molecular mass distributions proved to be sensitive to borane and alkylaluminum compounds molar ratios, [B]/[Nd] and [Al]/[Nd] using Nd(Oi-Pr)3 and [Cl]/[Nd] and [Al]/[Nd] with NdV3. | |
