Abstract

Official abstract text for this publication.

The invention provides a composition for the production of a fiber having organic solvent resistance, a fiber obtained by spinning the composition, and a biocompatible material containing the fiber. The composition contains (A) a polymer compound containing a unit structure represented by the formula (1) wherein each symbol is as described herein, (B) a crosslinking agent, (C) an acid compound, and (D) a solvent.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of producing a fiber, comprising spinning a composition comprising (A) a polymer compound consisting of monomer units represented by formula (1) that are the same or different wherein R 1 is a hydrogen atom or a methyl group, Q 1 is an ester bond or an amide bond, R 2 is an alkyl group having 1-10 carbon atoms or an aromatic hydrocarbon group having 6-10 carbon atoms, wherein at least one hydrogen atom is substituted by a hydroxy group, (B) a crosslinking agent, (C) an acid compound, and (D) a solvent to form a fiber. 2. The method according to claim 1 , wherein the spinning is electrospinning. 3. The method according to claim 1 , further comprising heating the fiber at 70-300° C. 4. A fiber produced by the method according to claim 1 . 5. A biocompatible material comprising the fiber according to claim 4 .
