Embodiments include curable compositions including an epoxy resin and a hardener component including a polymer having first constitutional unit, a second constitutional unit, and a third constitutional unit, where the epoxy group to the second constitutional unit has a molar ratio in a range of 0.5:1 to 5:1. Embodiments include prepregs that include a reinforcement component and the curable composition and an electrical laminate formed with the curable composition.

Curable compositions

Curable compositions comprising an epoxy mixture comprising a) an epoxy mixture comprising i) a first epoxy component comprising epoxy phenol novolac oligomers having a content of 2-functional monomers of less than 10 weight percent based on the total weight of the first epoxy component and having an epoxide equivalent weight in the range of 170 to 200; and ii) a second epoxy component comprising an epoxy resin having monomers with an average functionality of at least 2 and b) a hardener, are disclosed. The curable compositions can be used to prepare prepregs for hot-melt applications.

Curable epoxy compositions

Embodiments of the present disclosure provide a composition that includes a phosphorous-containing compound, a cyanate ester, an epoxy resin, and a maleimide. For the various embodiments, a viscosity of the composition increases less than 100% as measured by Gardner Bubble Viscosity a temperature of 23&#xb0; C. in at least 3 days. For the various embodiments, the composition of the present disclosure can also include an aprotic solvent, such as a ketone. Embodiments of the present disclosure further include a composition that includes the phosphorous-containing compound, the cyanate ester, and the aprotic solvent.
