| titleOfInvention | Production of polyamino acid urethane resin and its microporous film |
| abstract | PURPOSE:To obtain the title resin excellent in solution stability, heat resistance, etc., by reacting a specified alpha-amino acid N-carbonic anhydride/urethane prepolymer mixture with an amine in an active hydrogen-free organic solvent. CONSTITUTION:An alpha-amino acid N-carbonic anhydride (A) is obtained by mixing a neutral amino acid N-carbonic anhydride (a) of formula I (wherein R1 is a 3-7C alkyl, formula II or CH3SCH2CH2-), e.g., leucine, with 10-90wt.% omega-alkyl acidic amino acid N-carbonic anhydride (b) of formula III (wherein R1 is a 1-4C alkyl, formula IV and n is 1-2), e.g., gamma-methylglutamic acid. An amine (C) (e.g., isophoronediamine) is added to a mixture of component A with 10-90wt.% urethane prepolymer (B) in an active hydrogen-free organic solvent (e.g., dimethyl formamide), and the mixture is reacted at 10-60 deg.C to obtain the title resin. This resin is useful as a surface treating agent which, when applied to synthetic leather or synthetic fiber, can give thereto a hand equivalent to that of natural leather or natural fiber. |
