| 中文摘要 | a new method for synthesis of novel hyperbranched poly(ester-amide)s from commercially available aa' and cbx type monomers has been developed on the basis of a series of model reactions. the hyperbranched poly(ester-amide)s with multihydroxyl end groups are prepared by thermal polycondensation of carboxyl anhydrides (aa') and multihydroxyl primary amine (cbx) without any catalyst and solvent. the reaction mechanism in the initial stage of polymerization was investigated with in situ h-1 nmr. in the initial stage of the reaction, primary amino groups of 2-amino-2-ethyl-1,3-propanediol (aepo) or tris(hydroxymethyl)aminomethane (tham) react rapidly with anhydride, forming an intermediate which can be considered as a new ab(x) type monomer. further self-polycondensation reactions of the ab. molecules produce hyperbranched polymers. analysis using h-1 and c-13 nmr spectroscopy revealed the degree of branching of the resulting polymers ranging from 0.36 to 0.55. these hyperbranched poly(ester-amide)s contain configurational isomers observed by c-13 and dept c-13 nmr spectroscopy, possess high molecular weights with broad distributions and display glass-transition temperatures (t(g)s) between 7 and 96 degreesc. |
