HALOGEN-FREE PHOSPHOROUS- AND NITROGEN-CONTAINING FLAME-RESISTANT EPOXY RESIN COMPOSITIONS, AND PREPREGS DERIVED FROM THEREOF

摘要

Curable flame-resistant substantially halogen free epoxy resin compositions, comprising: (a) one or more bifunctional and/or polyfunctional epoxy resin; (b) at least two specific phosphorous-containing compounds; (c) a curing agent consisting of oligomers triazine modified cresol novolac comprising at least cresol condensate wherein a cresol compound (X) and a triazine compound (Y) have been condensed via aldehydes (Z), optionally (d) a curing catalyst and optionally (e) additives; prepregs derived from said compositions and laminates derived from said prepregs.
