1,4-Cyclohexanedimethanol-based polyesters derived from 1,4-cyclohexanedimethanol (CHDM) and aliphatic diacids with odd carbons
1,4-Cyclohexanedimethanol-based polyesters were synthesized from 1,4-cyclohexanedimethanol (CHDM) and a variety of aliphatic diacids with odd carbons. Differential scanning calorimetric analyzer (DSC), wide angle X-ray diffraction (WXRD), thermogravimetric analyzer (TGA), universal testing machine, dynamic mechanical analysis (DMA), and rotational rheometer were used for the characterization. Number-average molecular weight of CHDM-based polyesters is 12,000–37,000 g/mol. All polyesters can crystallize. All CHDM-based polyesters have good thermal stability. The polyesters from aliphatic diacids with long chains (azelaic acid, undecanedioic acid, and tridecanedioic acid) have better crystallization ability and good toughness (elongation at break > 300%). CHDM-based polyesters are potentially bio-based materials with great potential and promise.
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."
