Hyperbranched (hb) polymers have been receiving increasing attention because of their unique architecture that results in an interesting set of unusual chemical and physical properties. Over the past decade quite a number of excellent reviews on hb polymers have been published by different research groups, covering various aspects of this class of polymers. This review will highlight the work on aromatic hb polymers of the last decade, emphasizing general synthetic strategies and recent development of alternative synthetic strategies, and discussing various aspects of hb polymers to demonstrate their wide range of applications.

A series of flame retardant epoxy composites were prepared based on bisphenol A epoxy resin, T31 curing agent, intumescent flame retardant and CYH-277 toughener. The combustion and thermal degradation properties of the epoxy composites were evaluated by cone calorimeter test (CCT), thermogravimetric analysis (TGA), scanning electron microscopy and smoke density test (SDT) respectively. The CCT results showed that the addition of CYH-277 can decrease heat release rate, total heat release and smoke production rate, reduce the char residue, and delay the ignition time of flame retardant epoxy composites. EP-3 with 14 wt-% CYH-277 toughener comparatively showed the best flame retardancy among all samples. The TGA results showed that CYH-277 toughener had an influence on the initial decomposition temperature rather than on the char residues. In addition, the SDT results showed that EP-1 had the best smoke suppression ability.

A new reactive hyperbranched polyphosphate ester (HPPE) was synthesized by one step reaction. The structure of HPPE was characterized by 1 H NMR, FTIR, and inherent viscosity. High performance flame retardant modified benzoxazinebisoxazoline resins were obtained by the additional reaction with HPPE. Differential scanning calorimetry showed that there was an obvious shift in the exothermic peak of BPH5 (mass ratio of Ba-1,3-PBO and HPPE was 95:5) from 225 to 202°C, comparing with that of BPH0 (pure benzoxazine-bisoxazoline resins). It meant that the curing reaction could be catalyzed and accelerated by HPPE. The impact strength experiments illustrated that the maximum impact strength of modified resins may reach 19.2 kJ/m 2 . The char yield at 700°C of BPH5, BPH15, and BPH30 were 3.34, 4.47, and 7.75%, respectively. The benzoxazine-bisoxazoline resins modified by HPPE showed good flame retardancy.
