摘要:
Described is the preparation of sulfonated polyoxadiazole polymers with a high degree of sulfonation and good flammability properties. The polymers are useful in articles such as fibers.
摘要:
Disclosed herein are lignin-furfuryl alcohol compositions, lignin-furfuryl alcohol-resole (LFR) compositions comprising lignin-furfuryl alcohol composition and phenolic resoles and LFR foams derived from such LFR compositions. Disclosed herein are LFR foams comprising a polymeric phase defining a plurality of open cells and a plurality of closed cells, and a gas phase comprising one or more blowing agents disposed in at least a portion of the plurality of closed cells, wherein the polymeric phase is derived from LFR compositions.
摘要:

Disclosed herein are compositions and article made therefrom and processes of making them. The composition comprises a polymer, the polymer comprising a repeat unit of formula shown below: wherein the polymer is derived from an aromatic diamine comprising m-phenylene diamine, and an aromatic diacid or a derivative thereof comprising furan dicarboxylic acid or derivative thereof.
摘要:
A nonwoven web of poly(phenylene-1,3,4-oxadiazole) and polymetaphenylene isopthalamide. was found to have greater retention of tensile strength than kraft paper after immersion in oil at high temperature, making it useful as an insulation material for transformers.
