Polyethersulfone (PES) repeating unit. Polysulfones are a family of high performance thermoplastics. These polymers are known for their toughness and stability at high temperatures. Technically used polysulfones contain an aryl-SO 2-aryl subunit.

PES is chemi- cally made from bisphenol A and dichlorodiphenylsul- fone through a condensation reaction, and it proceeds through aromatic nucleophilic replacement mechanism [3,4].

2023年10月24日 · Polyethersulfone (PES or PESU) is relatively a new class of polymer and known since 1972 when first introduced by ICI. This high-temperature engineering thermoplastic has good transparency and flame resistance, and it …

Polyethersulfone (PES) is an amorphous, transparent, and pale amber high-performance thermoplastic and is the most temperature resistant transparent commercially available thermoplastic resin. It has relatively high water absorption. Stable solutions can be made if solvents are correctly chosen.

2014年1月1日 · Poly (ether sulfone) and polysulfone are polymers respectively containing ether and sulfone group in repeating units. Conventionally, they stand for the specific commercialized aromatic amorphous thermoplastics carrying para-linked diphenylenesulfone and aromatic ether in their repeating units.

Poly(ether sulfone) and polysulfone are polymers respectively containing ether and sulfone group in repeating units. Conventionally, they stand for the specific commercialized aromatic amorphous thermoplastics carrying para-linked diphenylenesulfone and aromatic ether in their repeating units.

2015年12月12日 · Polyethersulfone (also called 4,4′-sulfonyldiphenol polymer, poly(oxy-1,4-phenylenesulfonyl-1,4-phenylene), or poly(oxy-p-phenylsulfonyl-p-phenylene), abbreviated as PES) is an amorphous, transparent, and pale amber high-performance thermoplastic consisting of repeating phenyl groups linked by thermally stable ether and sulfonic (-SO 2-) groups.

2024年7月21日 · 本文将详细探讨pes化学结构及其分子式，以便读者更深入理解这种材料本质。 一，聚醚砜基本组成. 聚醚砜是一种由醚基(-o-)，砜基(-so2-)组成高分子聚合物。这些基团于分子链中交替排列，形成了pes特殊化学结构。

2023年1月18日 · Polyethersulfone has a somewhat straightforward structure, simply comprising linked phenyl and sulfone units. Both units add several distinct benefits to their build-ups and applications. For instance, we said the sulfone group is responsible for the high operational temperature stability it boasts.

2024年8月5日 · 聚醚砜基本结构单元是由硫醚（-SO2-），醚（-O-）基团交替连接苯环组成。 这种结构赋予了PES优良热稳定性，化学稳定性。 硫醚基团提供了较高极性，而醚基团则提供了一定柔韧性，使得PES既坚韧又耐用。 PES分子量及其分布对其加工性能，最终产品性能有着显著影响。 高分子量PES通常具有更好机械性能，热稳定性，但加工起来也许更为困难。 相反，低分子量PES虽然易于加工，但也许于机械强度，热稳定性方面表现不佳。 因此，控制PES分子量及 …
