Abstract
A method of preparing a capped poly(arylene ether) resin includes reacting a capping agent with a blend of two or more poly(arylene ether) resins having different intrinsic viscosities. Cured compositions prepared from these capped poly(arylene ether) resins exhibit improved balances of stiffness, toughness, and dielectric properties compared to compositions with two or more separately capped and isolated poly(arylene ether) resins.
Claims20
A method of preparing a capped poly(arylene ether) resin, comprising:
- reacting a capping agent with a blend of a first poly(arylene ether) resin and a second poly(arylene ether) resin, wherein the first poly(arylene ether) resin and the second poly(arylene ether) resin have intrinsic viscosities differing by at least 0.1 deciliters per gram, measured at 25° C. in chloroform.
The method of claim 7, wherein R6 is hydrogen or methyl, and R7 and R8 are hydrogen.
A cured composition, comprising the reaction product of:
- a capped poly(arylene ether) resin prepared by capping a blend of a first poly(arylene ether) resin and a second poly(arylene ether) resin, wherein the first poly(arylene ether) resin and the second poly(arylene ether) resin have intrinsic viscosities differing by at least 0.1 deciliters per gram, measured at 25° C. in chloroform;
- an alkenyl aromatic monomer;
- and
- an acryloyl monomer.
