Halogen-free flame-retardant epoxy resin formulations |
| abstract |
The invention relates to a process for preparing halogen-free epoxy resins which have been rendered flame-retardant, in which a halogen-free epoxy resin is reacted with a polyfunctional aldehyde or ketone and with a phosphinic acid derivative, wherein the phosphinic acid derivative contains at least one P-H-active structural unit =PH(O) and is used in amounts equivalent to the polyfunctionality of the aldehyde or ketone, and to a halogen-free epoxy resin which has been rendered flame-retardant and is obtainable with the aid of this process, to the use of the epoxy resin as a base material for the production of circuit boards and printed circuits, and to intermediates for preparing the epoxy resins. |
