A phosphorus-containing polyester composite and method of manufacturing the same is related to the field of compound formulation. The composite is prepared by condensation under certain conditions of (A) a poly-functional phosphorus-containing aromatic hydroxy compound; (B) a difunctional aromatic acryl chloride compound and (C) a monofunctional aromatic phenol compound used as a blocking agent. The composite is used as a curing agent for epoxy. The phosphorus-containing polyester composite is reacted with the epoxy group of the epoxy to obtain non-halogen and flame-retardant cured composite being environment friendly and having low dielectric, low dielectric loss factor and high heat resistance. It can be used in an integrated circuit board and used as a semiconductor packaging material.
