Cyanate resin blends and radomes including them

Certain embodiments are directed to cyanate resin blends comprising, for example, a mixture of a cyanate monomer and a cyanate oligomer. The resin blends are effective to provide a dielectric constant of less than 2.7, a glass transition temperature of at least 150 DEG C and a moisture absorption of...

Beschreibung
Zusammenfassung:	Certain embodiments are directed to cyanate resin blends comprising, for example, a mixture of a cyanate monomer and a cyanate oligomer. The resin blends are effective to provide a dielectric constant of less than 2.7, a glass transition temperature of at least 150 DEG C and a moisture absorption of less than 1.5%. Radomes using the resin are also described.
