合成了低分子量的聚苯醚,在浓度为0.5g/dl的氯仿溶液中于30℃测定,它的比浓粘度为0.04～0.18dl/g,而它的分子量分布为1.5～2.5。这种粉末状的低分子量聚苯醚有着高的耐热性和优异的电性能,可用于印制电路板材料和改性其他的树脂。
A low molecular weight polyphenylene ether is synthesized and has a reduced viscosity of 0.04 to 0.18 dl / g as measured at 30 ° C in a chloroform solution having a concentration of 0.5 g / dl and a molecular weight distribution of 1.5 to 2.5. This powdered, low molecular weight polyphenylene ether has high heat resistance and excellent electrical properties that can be used in printed circuit board materials and in the modification of other resins.
