| 中文摘要 | a new method for syntheses of hyperbranched poly(ester-amide)s from commercially available a(2) and cbx type monomers has been developed on the basis of a series of model reactions. the aliphatic and semiaromatic hyperbranched poly(ester-amide)s with multihydroxyl end groups are prepared by in situ thermal polycondensation of intermediates obtained from dicarboxylic acids (a(2)) and multihydroxyl primary amines (cbx) in n,n-dimethylformamide. analyses of ftir, h-1 nmr, and c-13 nmr spectra revealed the structures of the polymers obtained. the maldi-tof ms of the polymers indicated that cyclization side reactions occurred during polymerization. the hyperbranched poly(ester-amide) s contain configurational isomers observed by c-13 and dept c-13 nmr spectroscopy. the dbs of the polymers were determined to be 0.38-0.62 by h-1 nmr or quantitive c-13 nmr and dept 135 spectra. these polymers exhibit moderate molecular weights, with broad distributions determined by size exclusion chromatography ( sec), and possess excellent solubility in a variety of solvents such as n, n- dimethylacetamide, dimethyl sulfoxide, tetrahydrofuran, and ethanol, and display glass-transition temperatures (t(g)s) between -2.3 and 53.2 degrees c, determined by dsc measurements. |
