摘要:
After steps of esterification, epoxidation and ring-opening, a series of novel monomers of 5-hydroxyl-6-methacryloyloxy-3-alkylate, C(n)COOCh (n = 1, 2, 3, 4, 5) were synthesized. After that, the corresponding polymers (P(n)COOCh, n = 1, 2, 3, 4, 5) were obtained by free radical polymerization. The molecular structure, composition and thermal behaviors of monomers and polymers were confirmed by H-1 NMR, FTIR, single crystal diffractometer, GPC, DSC and TGA. The results indicate that although their molecular weights are not high, all the polymers have high glass transition (T-g) and degradation temperature. In addition, T-g gradually decreases with increasing of alkyl chain lengths, and the degradation temperature increases with the increase of carbon number. (C) 2012 Elsevier B.V. All rights reserved.
