Abstract
The invention provides a kind of prepolymer with 4-(N-maleimide phenyl)Ether (MPGE) epoxy resin and 4,4′-diphenylmethane bismaleimide (BMI) as reactants, with free radical initiator leading to reaction in solvents, and adding inhibitor after reaction, with the mole ratio of 0.05-0.5 for BMI and MPGE; the initiator usage is 0.01%-0.15% of mole total for reactant monomers; the solvent usage is 50%-70% of the total weight of the reactants; the inhibitor usage is half to double of mole amount of the initiator used. This kind of prepolymer can be used to produce high-performance thermosetting resin composition corresponding to the packaging requirements for electronic components and Integrated Circuits (IC).
