Claim 2
Dependent Claim
40 words
A curable homogeneous solvent-free resin formulation comprising a cyanate ester, an epoxy resin and a thermoplastic polymer having a glass transition temperature (Tg) of at least 150°C, said thermoplastic polymer being selected from the group consisting of polyarylates and polyetherimides.
Claim 3
Dependent Claim
15 words
