  具有固有微孔性的聚醚砜的合成与表征

  摘要：

  具有固有微孔性（PIM）的聚合物通常是采用螺旋结构的梯型聚合物。在本研究中，合成了一种新的非梯型聚醚砜型PIM，其中包含线性砜部分。Brunauer–Emmett–Teller的测量证实，由于存在尺寸为0.54–0.66 nm的微孔，因此合成的聚合物具有较高的比表面积（430–590 m 2 g -1）。新型PIM的固有孔隙率特性归因于砜和苯部分的共振结构。预期将来会使用含有砜或类似官能团的PIM合成新的气体分离膜。

  High heat polyethersulfone compositions are provided which possess unexpectedly high glass transition temperatures. The polyethersulfone compositions comprise structural units derived from fluorenone bisphenols such as 9,9-bis(4-hydroxyphenyl)fluorene, 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 9,9-bis(4-hydroxyphenyl)fluorene and 4,4′-bis((4-chlorophenyl)sulfonyl)-1,1′-biphenyl and exhibits a single glass transition of greater than 300° C.

  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.

  A nucleophilic substitution reaction to crosslink cyclodextrin (CD) polymer with rigid aromatic groups, providing a high surface area, mesoporous CD-containing polymers (P-CDPs). The P-CDPs can be used for removing organic contaminants from water. By encapsulating pollutants to form well-defined host-guest complexes with complementary selectivities to activated carbon (AC) sorbents. The P-CDPs can rapidly sequester pharmaceuticals, pesticides, and other organic micropollutants, achieving equilibrium binding capacity in seconds with adsorption rate constants 15-200 times greater than ACs and nonporous CD sorbents. The CD polymer can be regenerated several times, through a room temperature washing procedure, with no loss in performance.
