摘要:
A novel aromatic triol was synthesized and polycondensed with various diacid chlondes resulting in the preparation of a series of hydroxy-terminated hyperbranched polyamide-esters without gelation Structure and degree of branching of the ensuing polymers were confirmed by FTIR. H-1 and C-13 NMR analyses These thermally stable polymers were found to be Soluble in apiotic solvents Inherent vis and T-g values lie in the range of 0 15-0 21 dL/g and 74-112 degrees C, respectively (C) 2009 Elsevier Ltd All rights ieserved
