CAPPING OF POLYPHENYLENE ETHER RESIN

The invention relates to methods of capping poly(phenylene ether) resin having an intrinsic viscosity between 0.05 and 0.35 dl/g. More particularly, the methods comprise capping a poly(phenylene ether) resin having an intrinsic viscosity between 0.05 and 0.35 dl/g in a solvent to produce a capped po...

More Information
Summary:The invention relates to methods of capping poly(phenylene ether) resin having an intrinsic viscosity between 0.05 and 0.35 dl/g. More particularly, the methods comprise capping a poly(phenylene ether) resin having an intrinsic viscosity between 0.05 and 0.35 dl/g in a solvent to produce a capped poly(phenylene ether) resin having an intrinsic viscosity between 0.05 and 0.35 dl/g and isolating the capped poly(phenylene ether) resin by removal of the solvent, preferably in a process other than precipitation. The invention also relates to the capped poly(phenylene ether) resin having an intrinsic viscosity between 0.05 and 0.35 dl/g.
