The present teachings contemplate a method that includes a step of providing a first amount of esterified reaction product of an acid and an epoxy-based material. The esterified reaction product may be further reacted an epoxy resin to form a polymeric epoxy. The resulting material may have a generally linear backbone, foaming and curing capability and flame retardant properties.

The ceramic-resin composite body includes: 35 to 70% by volume of a sintered body having a monolithic structure in which non-oxide ceramic primary particles having an average major diameter of from 3 to 60 m and an aspect ratio of from 5 to 30 are three-dimensionally continuous; and 65 to 30% by volume of a thermosetting resin composition having an exothermic onset temperature of 180 C. or more and a curing rate of from 5 to 60% as determined with a differential scanning calorimeter, and having a number average molecular weight of from 450 to 4800, wherein the sintered body is impregnated with the thermosetting resin composition.

A Formula of a phosphorous fire-retardant hardener having fire-retardant and heat-resistant properties as well as a low-dielectric constant. With a preparation of glass-fiber laminated board, the hardener meets UL-94V fire-retardant requirements and has a dielectric constant 5 of 4.0 (1 GHz).

Compositions and methods for forming epoxy resin systems are provided. In one embodiment, a composition is provided for an epoxy resin system including an epoxy resin blend comprising an epoxy resin, a first curing agent selected from the group of a polyarylene alkylphosphonate, a polyarylene arylphosphonate, and combinations thereof, and a second curing agent.

A low-k, non-flammable dicyclopentdiene (DCPD)-derived polyether and a method of producing the same are introduced. Incorporation of a phosphorus group and a DCPD derivative into a low-k, non-flammable dicyclopentdiene (DCPD)-derived polyether enable the DCPD-derived polyether to not only serve as an epoxy resin curing agent but also cure itself such that the cured product not only features satisfactory thermal properties and low-k characteristics but is also non-flammable.

The embodiments relate to a polymerisable thermoset composition having improved flame retardant properties, a polymerised thermoset having improved flame retardant properties, a process for manufacturing the polymerised thermoset, and use of the polymerisable thermoset composition to produce lightweight construction components, preferably carbon fibre composites (CFRP), and a lightweight construction component, preferably carbon fibre composite (CFRP), containing the polymerised thermoset.
