ABSTRACT:
A solventless thermosettable composition comprising a dialkenylbenzene and an effective amount of an alkylbenzenesul fonic acid curina aqent exhibits reduced tendency to gel during cure with the addition of a polyarylamine. The cured material, which is particularly useful in electrical/electronic applications, exhibits low dielectric constant and good fracture toughness.
