NOVEL COMPOSITION FOR PREPARING POLYSACCHARIDE FIBERS |
摘要 |
Solutions formed by combining poly(α(1→3) glucan) with CS2 in aqueous alkali metal hydroxide solution have been shown to produce the xanthated form of the poly(α(1→3) glucan). The solutions so formed have been shown to be useful for solution spinning into fiber of poly(α(1→3) glucan) when the spun fiber is coagulated in an acidic coagulation bath. The fibers so produced exhibit desirable physical properties. The poly(α(1→3) glucan) employed was synthesized by fermentation. |
