Abstract
A curable flame retardant epoxy resin composition including (a) at least one flame retardant epoxy resin; (b) at least one amphiphilic block copolymer; and (c) a curing agent. Such components are present in the curable composition in the appropriate amounts and ratios such that, upon curing, the block copolymer self-assembles into a nano structure morphology, such as a worm-like micelle morphology. The resulting cured product made from the composition of the present invention has a remarkably increased high fracture resistance; and allows the use of flame retardant epoxies in applications where fracture resistance is an issue.
Claims26
A curable flame retardant epoxy resin composition with increased toughness comprising:
- (a) at least one curable flame retardant epoxy resin;
- (b) an amphiphilic block copolymer in an amount such that said amphiphilic block copolymer self assembles into micellar morphologies and such that the fracture resistance of the resulting cured product increases;
- and
- (c) a curing agent.
A process for preparing a curable resin composition comprising mixing:
- (a) at least one curable flame retardant epoxy resin;
- (b) an amphiphilic block copolymer in an amount such that said amphiphilic block copolymer self assembles into micellar morphologies and such that the fracture resistance of the resulting cured product increases;
- and
- (c) a curing agent.
A cured resin product comprising a flame retardant epoxy resin containing a block copolymer self-assembled into a worm-like micelle morphology.
A process for preparing a cured resin product comprising heating a mixture of:
- (a) at least one curable flame retardant epoxy resin;
- (b) an amphiphilic block copolymer in an amount such that said amphiphilic block copolymer self assembles into micellar morphologies and such that the fracture resistance of the resulting cured product increases;
- and
- (c) a curing agent.
