Synthesis, characterization, and modification of hyperbranched poly(arylene oxindoles) with a degree of branching of 100%

Smet, Mario,Schacht, Etienne,Dehaen, Wim

, p. 4547 - 4550 (2007/10/03)

Excellent thermal stability and a relatively high glass-transition temperature are exhibited by the hyperbranched poly(arylene oxindoles), which were prepared by an acidcatalyzed polycondensation of the substituted isatine 1. The polymers thus obtained ca
