摘要： PURPOSE:To produce the titled polyurethane capable of forming a molding excellent in light resistance, NOX gas resistance, flexibility, etc. by reacting a polymer diol with an alicyclic diisocyanate compound and isophthalic acid dihydrazide in a specified manner. CONSTITUTION:A hydroxyl group-terminated polymer diol (A) of an average MW of 1,000-3,500 (e.g., polycaprolactone glycol) is reacted with an alicyclic diisocyanate compound (B) (e.g., dicyclohexylmethane 4,4-diisocyanate) at a molar ratio of 1:1.2-1.9 until the terminal hydroxyl groups in component A are substantially completely eliminated. To the obtained isocyanato group-terminated prepolymer, component B in an amount to provide a molar ratio of component A to component B in the produced polyurethane of 1:2.5-6 and isophthalic acid dihydrazide are added, and the resulting mixture is reacted to obtain a polyurethane.

摘要： PURPOSE: To provide a macrophage activating agent containing a styrenemaleic acid copolymer or its half-ester derivative (some of which are novel) as an active component, capable of activating macrophage and useful for the prevention and remedy of malignant tumor.
CONSTITUTION: The objective agent contains a styrene-maleic acid copolymer or its half-ester derivative as an active component. The half-ester derivative is e.g. a half-alkyl or half-alkoxyethyl-ester derivative (alkyl and alkoxy are 1W8C straight or branched chain group), and some of the derivatives are novel. It has been known that the gydrogen peroxide produced ultimately by macrophage via a superoxide has antitumor activity. In view of the above findings, the copolymer or ester capable of activating macrophage and having excellent effect to produce the oxygen metabolite, is used as a carcinostatic agent or an agent to promote the activity of other carcinostatic agents.

摘要： PURPOSE:To perform the desorption of PVA polymers adsorbed on silica, by using an aqueous solution containing a specific concentration range of a specific water- soluble organic solvent, e.g., ethanol. CONSTITUTION:The desorption of PVA-based polymer containing 60molt% or more water-soluble polymer (PVA), for example, adsorbed in the form of an aqueous solution on silica, is performed using an aqueous solvent composed of an aqueous solution containing 1-35vol% organic solvent, e.g., ethanol, isopropanol, etc., at a temperature above 0 deg.C. The aqueous solution containing PVA-based polymer is passed through a silica gel-packed column so as to cause the PVA-based polymer to be adsorbed on the silica gel, and then the said solvent for desorption is passed through the said column for desorption of the PVA-based polymer, whereby permitting the recovery of PVA-based polymers from PVA-based polymer-containing aqueous solutions.
