Abstract:
PROBLEM TO BE SOLVED: To provide a transparent impact resistant improved polystyrene with favorable balance in the ratios of toughness and stiffness without conventional drawbacks. SOLUTION: The block copolymer is produced from an aromatic vinyl monomer and contains at least two hard blocks S 1 and S 2 . The block copolymer contains at least one random soft block B/S produced from the aromatic vinyl monomer and a diene between the hard blocks S 1 and S 2 , and contains less than 20% of 1,2-vinyl in the soft block B/S and has the hard block ratios at 51-74 mass% in the total block copolymers without containing a single polymer block B composed of the diene.

Abstract:
PROBLEM TO BE SOLVED: To provide an improved method for producing an amine from an alcohol, an aldehyde, and a ketone by using a catalyst which has improved mechanical properties and economically improves the conventional method using the catalyst containing zirconium dioxide. SOLUTION: The method for producing the amine comprises reacting a primary or secondary alcohol, an aldehyde or a ketone, hydrogen, and a nitrogen compound selected from among ammonia, a primary amine, and a secondary amine in the presence of the catalyst prepared by precipitating a catalytically active component on monoclinic, tetragonal, or cubic zirconium dioxide.

Abstract:
PROBLEM TO BE SOLVED: To obtain a protein which can neutralize the action of TNFα (tumor necrusis factor α). SOLUTION: This protein has molecular weight of about 42,000 daltons measured by SDS gel electrophoresis and has at the N-terminus an amino acid sequence; Xaa Thr Pro Tyr Ala Pro Glu Pro Gly Ser Thr Cys Arg Leu Arg Glu (Xaa is H, phenylalanine residue (Phe) or an amino acid sequence; Ala Phe, Val Ala Phe, Gln Val Ala Phe, Ala Gln Val Ala Phe, Pro Ala Gln Val Ala Phe or Leu Pro Ala Gln Val Ala Phe), and a mutein is obtained by subjecting the protein having the TNFα suppressing action to a proper substitution, deletion or addition of an amino acid or peptide or the change of a glycoside group without strongly lowering the TNFα suppressing action.
