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).
1 . A composition for forming a fiber, comprising (A) a polymer compound containing a unit structure represented by the formula (1), (B) a crosslinking agent, (C) an acid compound, and (D) a solvent: 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. 2 . The composition according to claim 1 , wherein the above-mentioned polymer compound has a weight average molecular weight of 1,000-1,000,000. 3 . The composition according to claim 1 , wherein the above-mentioned solvent is a polar solvent. 4 . A production method of a fiber, comprising a step of spinning the composition according to claim 1 . 5 . The method according to claim 4 , wherein the above-mentioned spinning is electrospinning. 6 . The method according to claim 4 , comprising a step of heating a spun fiber at 70-300° C. 7 . A fiber produced by the method according to claim 4 . 8 . A biocompatible material comprising the fiber according to claim 7 . 9 . A fiber comprising (A) a polymer compound containing a unit structure represented by the formula (1), (B) a crosslinking agent, and (C) an acid compound: 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.
