Synthesis and Characterization of α-End Functionalized 3,4-Polyisoprene Using Fe(acac)3/IITP/AliBu3 Catalyst
The synthesis of functionalized rubber copolymers is a topic of great research interest. In this study, we present a novel approach for the direct construction of α-functionalized 3,4-polyisoprene through polymerization of polar monomers and isoprene monomer. The α-functionalized 3,4-polyisoprene was successfully synthesized via in situ sequential polymerization using the iron-based catalytic system (Fe(acac)3/IITP/AliBu3), exhibiting high activity and resistance to polar monomers without requiring protection of polar groups. The structure of α-functionalized 3,4-polyisoprene was confirmed by proton nuclear magnetic resonance spectroscopy (1H-NMR) and two-dimensional diffusion-ordered spectroscopy (2D DOSY) spectra analysis. The introduction of polar groups, particularly hydroxyl groups, enhanced the hydrophilicity of the copolymer. This was evidenced by a decrease in the water contact angle from 106.9° to 96.4° with increasing hydroxyl content in the copolymer.
期刊介绍：
Chinese Journal of Polymer Science (CJPS) is a monthly journal published in English and sponsored by the Chinese Chemical Society and the Institute of Chemistry, Chinese Academy of Sciences. CJPS is edited by a distinguished Editorial Board headed by Professor Qi-Feng Zhou and supported by an International Advisory Board in which many famous active polymer scientists all over the world are included. The journal was first published in 1983 under the title Polymer Communications and has the current name since 1985.
CJPS is a peer-reviewed journal dedicated to the timely publication of original research ideas and results in the field of polymer science. The issues may carry regular papers, rapid communications and notes as well as feature articles. As a leading polymer journal in China published in English, CJPS reflects the new achievements obtained in various laboratories of China, CJPS also includes papers submitted by scientists of different countries and regions outside of China, reflecting the international nature of the journal.
