A composition containing a semicrystalline poly(2,6-dimethyl-l,4-phenylene ether) having a glass transition temperature of 205 to 225 °C can be compression molded under conditions that include a molding temperature substantially below the glass transition temperature. In some cases, the crystallinity of the poly(2,6-dimethyl-l,4-phenylene ether) increases substantially during molding, even though the molding temperature is below the glass transition temperature. Also described are articles formed by the molding method, articles in which the poly(2,6-dimethyl-l,4-phenylene ether) has a crystallinity of at least 5 weight percent, and a method of increasing the crystallinity of poly(2,6-dimethyl-l,4-phenylene ether). |
