Abstract
In this article, statistical copolymers of N-vinylpyrrolidone and phenoxyethyl methacrylate were successfully prepared by reversible addition–fragmentation chain transfer polymerization (RAFT), using [O-ethylxanthyl)methyl]benzene as a chain transfer agent (CTA). The reactivity ratios of the system were calculated using the Fineman–Ross, inverted Fineman–Ross, Kelen–Tüdos and extended Kelen–Tüdos graphical methods along with the computer program COPOINT, with the latter providing the most accurate results for the penultimate model. The thermal properties were examined via DSC and TGA, with P(NVP-stat-POEMA) 50–50 displaying the highest thermal stability. Finally, the micellization behavior in a selective solvent was explored, indicating the formation of monomolecular micelles for all samples.
期刊介绍：
"Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad.
"Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
