    • A method for making resinous phosphorus-containing polyarylene ethers of the structure ##STR1## wherein R taken alone is hydrogen or R R taken together are a covalent single bond, oxygen, sulfur, or a sulfonyl, carbonyl, methylene or isopropylidene bridge;R' is alkyl or aryl;R" is a single bond, oxygen, sulfur, or an organic group having from 5 to 15 carbon atoms whose free valences emanate from quaternary carbon atoms;E is an end group which is chlorine, hydrogen, alkyl, aryl, or acyl; andn has an average value of at least 10,by polycondensing appropriate bis(chlorophenyl)phosphine oxides with appropriate bisphenols at an elevated temperature in the presence of alkali in reaction times of at least 10 hours, and certain resinous ethers produced by this method.
    • 制备具有结构单元的树脂含磷聚亚芳基醚的方法其中单独使用的是氢或R R一起为共价单键,氧,硫或磺酰基,羰基,亚甲基或异丙叉桥; R'是烷基或芳基; R“是单键,氧,硫或具有5至15个碳原子的有机基团,其自由价从季碳原子发出; E是氯,氢,烷基,芳基或酰基的端基; 并且n的平均值至少为10,通过在适当的双(氯苯基)氧化膦与适当的双酚在高温下在碱的存在下,在至少10小时的反应时间和通过该方法生产的某些树脂醚进行缩聚。
