  • Patent number: 9975992
    Abstract: 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.

  • Patent number: 9956742
    Abstract: A composite, a high-frequency circuit substrate using the same and method thereof are discussed. The composite includes the following solid components: a DOPO (9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide) derivative compound of 10-70 wt %, a curing agent of 10-50 wt %, one or more epoxy of 10-90 wt % and an inorganic filling material of 10-40 wt %. The non-halogen low dielectric epoxy composite uses a high-purity DOPO (9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide) derivative as tiny particles dispersing in the composite. The crosslinking yield of the composite is not reduced, while the heat resistance and flame retardancy are increased. The prepreg and copper foil covered laminate for use in printed circuit board, made from the epoxy composite, has great dielectric property and high glass transition temperature (GTT), satisfying the need of high frequency in electronic signal transmission and high speed in data processing of the industry of copper covered printed circuit board.
