    • High heat polyethersulfone compositions are provided which possess unexpectedly high glass transition temperatures. The polyethersulfone compositions comprise structural units derived from phthalimide bisphenols such as 3,3-bis(4 -hydroxyphenyl)-N-phenylphthalimide, and structural units derived from at least one biphenyl-bissulfone such as 4,4′-bis((4-chlorophenyl)sulfonyl)-1,1′-biphenyl. The novel polyethersulfone compositions may further comprise structural units derived from one or more biphenols such as 4,4′-biphenol, bisphenols such as BPA, or other electrophilic sulfone monomers, such as bis(4-chlorophenyl)sulfone. In one embodiment, the polyethersulfone composition of the present invention comprises structural groups derived exclusively from 3,3-bis(4-hydroxyphenyl)-N-phenylphthalimide, and 4,4′-bis((4-chlorophenyl)sulfonyl)-1,1′-biphenyl and exhibits a single glass transition of greater than 300° C.
    • 提供了具有出人意料的高玻璃化转变温度的高热聚醚砜组合物。 聚醚砜组合物包含衍生自邻苯二甲酰亚胺双酚的结构单元,例如3,3-双(4-羟基苯基)-N-苯基邻苯二甲酰亚胺,以及衍生自至少一种联苯基 - 砜的结构单元,例如4,4'-双((4- 氯苯基)磺酰基)-1,1'-联苯。 新型聚醚砜组合物还可以包含衍生自一种或多种双酚的结构单元,例如4,4'-联苯酚,双酚如BPA或其它亲电子砜单体如双(4-氯苯基)砜。 在一个实施方案中,本发明的聚醚砜组合物包含仅由3,3-双(4-羟基苯基)-N-苯基邻苯二甲酰亚胺衍生的结构基团和4,4'-双((4-氯苯基)磺酰基) 1'-联苯并且表现出大于300℃的单一玻璃化转变。

    • A polyethersulfone composition is disclosed which comprises structural units derived from bisphenol-A and 4,4′-biphenol, the structural units derived from 4,4′-biphenol being present in an amount corresponding to greater than 65 mole percent based on total moles of structural units derived from diphenolic monomers, wherein the polyethersulfone has a weight average molecular weight (Mw) of at least 54,000 grams per mole as measured by gel permeation chromatography. The polyethersulfone compositions of the invention display outstanding impact strength as measured using ASTM D256. Surprisingly, the polyethersulfone compositions of the invention show enhanced impact strength relative to known polyethersulfones such as RADEL R, a commercially available polyethersulfone engineering thermoplastic comprised of structural units derived from a dihalodiarylsulfone and 4,4′-biphenol and having a Notched Izod impact strength of about 700 Joules per meter.
    • 公开了一种聚醚砜组合物,其包含衍生自双酚A和4,4'-联苯酚的结构单元,衍生自4,4'-联苯酚的结构单元的存在量相当于基于总共摩尔数 衍生自二元酚单体的结构单元,其中聚醚砜的重均分子量(Mw)通过凝胶渗透色谱法测定为至少54,000克/摩尔。 本发明的聚醚砜组合物显示出优异的冲击强度,使用ASTM D256测量。 令人惊奇的是,本发明的聚醚砜组合物相对于已知的聚醚砜如RADEL R显示出增强的冲击强度,RADEL R是由二卤代芳基砜和4,4'-联苯酚衍生的结构单元的市售聚醚砜工程热塑性塑料,其具有缺口伊佐德冲击强度 约700焦耳/米。
