Abstract: A method of removing substantially all solvent from a solution containing a polyphenylene ether polymer resin with little by-product formation (less than 250 ppm) is provided. The method employs a wiped thin film evaporator with a cylindrical heating chamber operating under conditions that satisfy the relationships defined by Equations I and II: 5.3*10 RL delta exp( )/m

Abstract: A method of preparing a poly(arylene ether)includes oxidatively polymerizing a monohydric phenol in solution, concentrating the solution by removing a portion of the solvent to form a concentrated solution having a cloud point, Tcloud, and combining the concentrated solution with an anti-solvent to precipitate the poly(arylene ether), wherein the concentrated solution has a temperature of at least about (Tcloud-10 DEG C) imme diately before it is combined with the anti-solvent. The method reduces the formation of undesirably fine particles in the product poly(arylene ether).

Abstract: Thermosetting polymers and the electrical laminates made therefrom are disclosed. The laminate comprises a cross-linked product of: a) one or more ethylenically unsaturated aromatic monomers, with fire retardation being optionally contributed by one halogenated monomer; b) a vinyl-terminated polybutadiene or butadiene-styrene copolymer containing either a urethane or an ester group; and c) a chemically modified polyphenylene ether resin, preferably low molecular weight chemically modified polyphenylene ether resin. It has been discovered that an unexpected combination of thermal, electrical, and mechanical properties are obtained from the composition recited herein. Therefore, the composition is ideally suited as a matrix polymer for electrical substrate applications.
