METHOD OF PRODUCING THERMOSETTING AROMATIC POLYESTER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a method of producing a uniform thermosetting aromatic polyester composition that makes it possible to suppress an increase in viscosity of the thermosetting aromatic polyester composition at the time of melt-mixing a thermosetting aromatic polyester and a thermosetting agent.SOLUTION: This method for producing a thermosetting aromatic polyester composition comprises: a step (I) for melt-mixing an aromatic polyester (A) and an additive; and a step (II) for adding a cross-linking compound (B) to the mixture obtained at step (I), and melt-mixing the same.
