  • CAPPED POLY(ARYLENE ETHER) COMPOSITION AND METHOD
    Publication number: 20040106750
    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.

  • Compositions comprising functionalized polyphenylene ether resins
    Publication number: 20040102583
    Abstract: The invention relates to a method of forming a polyphenylene ether resin containing residual aliphatic unsaturation. A polyphenylene ether is reacted with a capping agent in a solvent to form the polyphenylene ether resin containing residual aliphatic unsaturation, which is precipitated from solution by combining the solution with an antisolvent. The precipitated polyphenylene ether resin containing residual aliphatic unsaturation has lower levels of residual impurities than the same compound isolated by devolatilization.

  • Preparation of acrylic polyols
    Publication number: 20030069440
    Abstract: A process for making acrylic polyols from allylic alcohols is disclosed. The process is performed essentially in the absence of styrene and in the absence of methyl acrylate or methacrylate. It comprises initially charging a reactor with an allylic alcohol, 0-75% of the total amount to be used of an acrylic monomer, and 0-100% of the total amount to be used of a free-radical initiator. The reaction mixture is heated to a temperature within the range of about 100° C. to about 250° C. The remaining acrylic monomer and initiator are gradually added into the reactor during the course of polymerization. The monomer conversion is greatly enhanced as a result of using essentially no styrene.
