    • Copolyetherimides compositions having high glass transition temperatures and outstanding ductility are presented. The copolyetherimides having Mw of at least 40,000 comprising isomeric bis(phthalimide) structural units within a relatively narrow range of isomer proportions exhibited Tgs of at least 240° C. and outstanding Notched Izod values. The copolyetherimides comprise oxydianiline residues and structural units of the formulas (I) and (II) (III). The copolyetherimides are characterized by a mole percentage of structural units derived from 4,4′-biphenol in a range from about 55% to about 85% of all bisphenol-derived structural units present in the copolyetherimide composition; a mole percentage of structural units derived from bisphenol A in a range from about 45% to about 15% of all bisphenol-derived structural units present in the copolyetherimide composition; and a total mole percentage of structural units derived from bisphenol A or 4,4′-biphenol of at least 95% of all bisphenol-derived structural units present in the copolyetherimide composition.
    • 提出了具有高玻璃化转变温度和优异延展性的共聚酰亚胺组合物。 具有至少40,000的含有异构双(邻苯二甲酰亚胺)结构单元的异构体双组分(邻苯二甲酰亚胺)结构单元的共聚醚酰亚胺具有至少240℃的Tg和优异的缺口伊佐德值。 共聚醚酰亚胺包括氧化二苯胺残基和式(I)和(II)(III)的结构单元。 共聚醚酰亚胺的特征在于衍生自4,4'-联苯酚的结构单元的百分比在共聚醚酰亚胺组合物中存在的所有双酚衍生的结构单元的约55%至约85%的范围内; 来自双酚A的结构单元的摩尔百分比在存在于共聚醚酰亚胺组合物中的所有双酚衍生的结构单元的约45%至约15%的范围内; 并且衍生自双酚A或4,4'-联苯酚的结构单元的总摩尔百分比为存在于共聚醚酰亚胺组合物中的所有双酚衍生的结构单元的至少95%。

    • Novel metal porphyrin compositions useful as organic phosphors are provided. The novel compositions are prepared from commercially available porphyrin-containing starting materials. In one instance a novel palladium-containing porphyrin composition having a number average molecular weight of greater than 12,000 grams per mole was prepared from 5,10,15,20-tetrakis(3′,5′-di(hydroxy)phenyl)-21H-23H-porphyrin by reaction first with palladium(II) acetylacetonate, followed by reaction with 2-bromo-2-methylpropionyl bromide, and subsequent group transfer reaction of the alpha-bromo ester groups with 9,9-dioctyl-2-vinylfluorene in the presence of CuBr as a radical initiator. The product polymer exhibited a number average molecular weight of 12,884 grams per mole, a weight average molecular weight of 14,338 grams per mole, and a robust red phosphorescent emission. Porphyrin containing copoylmers comprising structural units derived from 9,9-dioctyl-2-vinylfluorene and 9-anthracenylmethyl methacrylate were prepared in a similar fashion.
    • 提供了可用作有机磷光体的新型金属卟啉组合物。 该新型组合物由市售的含卟啉原料制备。 在一种情况下,从5,10,15,20-四(3',5'-二(羟基)苯基)-21H(5')中制备数均分子量大于12,000克/摩尔的新颖的含钯卟啉组合物 -23H-卟啉通过首先与乙酰丙酮钯(II)反应,随后与2-溴-2-甲基丙酰溴反应,随后将α-溴酯基与9,9-二辛基-2-乙烯基芴的组转移反应 存在CuBr作为自由基引发剂。 产物聚合物的数均分子量为12,884克/摩尔,重均分子量为14,338克/摩尔,并具有坚固的红色磷光发射。 含有衍生自9,9-二辛基-2-乙烯基芴和9-蒽基甲基甲基丙烯酸酯的结构单元的含卟啉的共聚酰基酯以类似的方式制备。
