Abstract

There is disclosed a novel mixture of polyhydroxy phenolic curing agents, such as novolac resins blended with a mixture of mono, bis and tris hydroxyaryl phosphine oxides for co-curing epoxy resins and imparting flame resistance thereto. A preferred composition includes a mixture of monohydroxyaryl, bishydroxyaryl and trishydroxyaryl phosphine oxide and a benzoguanamine/phenol/formaldehyde terpolymer which is used along with an epoxy resin to produce flame-resistant printed wiring boards without the use of halogens.

Claims (21)

1. A resin-impregnated composite comprising a reinforcing component and a flame retardant epoxy composition comprising:

(a) an epoxy resin;

(b) a co-crosslinking polyhydroxy mixture including:

(i) a mixture of phosphine oxides including hydroxyaryl phosphine oxides of the formulae:

(A) a mono(hydroxyaryl)phosphine oxide of the formula:

wherein R 1 is a divalent substituted or unsubstituted arylene moiety and R 2 is a monovalent substituted or unsubstituted aryl moiety or is an alkyl moiety or is an aralkyl moiety; and

(B) a bis(hydroxyaryl)phosphine oxide of the formula:

wherein R 1 and R 2 are defined as above, and

(C) a tris(hydroxyareyl)phosphine oxide of the formula:

wherein R 1 is defined as above; and

(D) optionally containing minor amounts of a pentavalent phosphine oxide of the formula:

wherein R 2 is defined as above; and

(ii) a phenolic co-crosslinking composition comprising a phenolic component having a hydroxy functionality of two or more,

at least partially cured.

2. The resin-impregnated composite according to claim 1 , including a glass filler, a glass fiber or a glass fabric.

3. The resin-impregnated composite according to claim 2 , wherein said composite includes a glass fabric.

4. A laminate, optionally including a copper foil layer adhered to the resin-impregnated composite of claim 1 .

5. A laminate, optionally including a copper foil layer adhered to the resin-impregnated composite of claim 2 .

6. A laminate, optionally including a copper foil layer adhered to the resin-impregnated composite of claim 3 .

7. The laminate according to claim 6 , wherein said laminate includes a plurality of layers of resin-impregnated glass fabric, press-formed into a substantially integrated structure generally inseparable into its constituent layers.

8. The laminate according to claim 7 , wherein the epoxy resin is based on epichlorohydrin and bisphenol A, epichlorohydrin and bisphenol F, or is a novolac epoxy resin.
