    Abstract: Provided is a pentaaryldiamine-containing bismaleimide compound of Formula (I): wherein Ar1 to Ar5 are independently C6-C12 aryl; and Ar4 and Ar5 are optionally substituted by one or more substitutent(s) selected from the group consisting of C1-C6 alkyl, C1-C6 alkoxy, and cyano. The compound of Formula (I) is obtained by a method including the steps of reacting a diamine with maleic anhydride in a solvent to form an amic acid, and cyclodehydrating the amic acid in the presence of a catalyst and a dehydrating agent. The compound of Formula (I) has a nonlinear and asymmetric structure, is amorphous, and is readily soluble in a variety of organic solvents so that the toughness of the product made there from can be improved and processing of the compound can be simplified.

    Abstract: The invention provides hyper-branched polymer manufactured by adding a bismaleimide and a barbituric acid into a Brönsted base solution and reacting the mixture at 20 to 100° C. The formation may further include maleimide monomer and/or multi-maleimide monomer to modify the hyper-branched polymer properties. In addition, the barbituric acid is added to the reaction in a batch not initially charged with other reactants in a one-pot.
