In order to investigate their potential applications as additives, we synthesized the allyl-terminated hyperbranched PAEKs (HBP-AL) via an etherification between HBP-OH and allyl bromide and incorporated HBP-AL into the bismaleimide (BMI) resins based on 4,4'-bismaleimideodiphenylmethane (BMDM, Chart 1) and 2,2'-diallylbisphenal A (DBA).
