Sulfonated polyether sulfone 'S-PES'
Sulfonation of polyether sulfone (PES)! We have successfully achieved a high introduction rate of sulfonic acid groups while preventing a decrease in molecular weight.
KONISHI Chemical Industry Co., Ltd. has developed sulfonated polyether sulfone 'S-PES' by sulfonating polyether sulfone (PES). The sulfonic acid group exhibits ion exchange capacity and hydrophilicity, imparting new functions to existing polymer compounds. A novel sulfonation method for aromatic polymers has been developed, successfully achieving a high sulfonic acid group introduction rate while preventing a decrease in molecular weight. (Patent No. 5824734) 【Quality Example】 ■ Appearance: Light brown powder ■ Sulfonic acid group introduction rate: 30% ■ Weight average molecular weight: 130,000 ■ Moisture: ≦3% ■ Development stage: Pilot results available *For more details, please refer to the PDF document or feel free to contact us.
