Abstract
Abstract Polymeric compositions are prepared from ethylenically unsaturated monomeric compositions and polyarylcyanate ester compositions which have at least two arylcyanate ester moieties bridged by a polycyclic aliphatic moiety; and wherein the polyarylcyanate ester composition is substantially soluble in the ethylenically unsaturated monomeric composition.
