101 Production of highly polymeric gelatin JP5874990 1990-03-09 JPH03259928A 1991-11-20 TANI TAKEHIRO; MOTODA TORU; MOTOKI MASAO
PURPOSE: To obtain a highly polymeric gelatin having a high m.p., a high viscosity and a high molecular weight and being useful for edible film, medicinal capsules, etc., by adding a specified amount of transglutaminase to a gelatin solution of a specified concentration and deactivating the enzyme after the reaction. CONSTITUTION: 0.1 unit or above, per g of the gelatin, of transglutaminase is added to a gelatin solution of a 0.1-5wt.% concentration, and the enzyme is deactivated after the reaction.

102 Dehydration and pulverization of polymer substance JP12967389 1989-05-23 JPH0258542A 1990-02-27 HAJI AKIRA; KIMURA KAZUJI; HASHIMOTO KOICHI
PURPOSE: To extremely readily dehydrate a large quantity of water and obtain a dry substance by freezing a hydrated gel or hydrated sol of a hydrophilic polymer, then dipping the frozen substance into a hydrophilic organic solvent for defrosting. CONSTITUTION: A hydrated gel or sol of a hydrophilic polymer substance is frozen and the resultant frozen substance is dipped into a hydrophilic organic solvent for defrosting. The resultant defrosted substance is dried and ground into a powdery hydrophilic polymer substance. The hydrated gel or sol which is the object of the application of the above-mentioned method is composed of 1 pt.wt. hydrophilic polymer substance containing 0.2-(300-500) pts.wt. water. For example, in case of curdlan, gelatin, agar, etc., the range of the application is 10-50 pts.wt. water content based on 1 pts.wt. of the above-mentioned substance. COPYRIGHT: (C)1990,JPO&Japio
103 New polymer composition JP12303989 1989-05-18 JPH0220564A 1990-01-24 JIYAKOBU SHIRUBIGERU; ROBAATO FUREDERITSUKU TOOMASU
PURPOSE: To provide a polymer composition useful as a solid article, such as a sheet or a bottle, and a carrier material for a chemical, etc., by adding a water-insoluble synthetic thermoplastic polymer to a water-containing hydrophilic polymer, and melting and mixing them in a sealed container at elevated temperature and at increased pressure. CONSTITUTION: One kind or more of substantially water-insoluble synthetic thermoplastic polymers (e.g. PE) are added to one kind or more of hydrophilic polymers (e.g. gelatin) having a water content of preferably 5-25 wt.% of the total amounts of the hydrophilic polymer/water and, if necessary, containing other additive (e.g. lubricant: calcium stearate), and they are melted and mixed together by heating in a sealed container at an elevated temperature and under pressure increased thereby, for a sufficient time to produce a molten body, so as to obtain a polymer composition comprising a molten body including one kind or more of water-containing decomposition hydrophilic polymers and one kind or more of substantially water-insoluble synthetic thermoplastic polymers.

109 Curing method of gelatin JP22345784 1984-10-24 JPS61100743A 1986-05-19 OKAMURA HISASHI; KAWAMOTO HIROYUKI
PURPOSE: To cure the gelatin with a high efficiency by incorporating a specific compd. to the gelatin, thereby reacting the compd. to a reactive residue contd. in the gelatin with a good selectivity. CONSTITUTION: The specific compd. shown by the formula is used as a curing cmopd. In the formula, R 2 and R 3 together with each other preferably form a ring, more preferably a pyrroliding ring. R 1 and R 2 together with each other rpeferably form a ring, more preferably a pyridine ring. R 4 and R 5 may be a substd. group such as a halogen substd. group. X - is an anion and comprises more preferably Cl -, BR 4 -, PF 6 - and a sulfonate ion. COPYRIGHT: (C)1986,JPO&Japio

115 Gelatin hardening method JP10281479 1979-08-14 JPS5627135A 1981-03-16 KOBAYASHI MORIO; SASAKI TAKASHI
PURPOSE: To obtain a hardened film withstanding high temp. rapid processing and automatic processing with a powerful developer by using the partial hydrolyzate of a dichloro-S-triazine deriv. to harden gelatin, especially the gelatin film of a photographic material. CONSTITUTION: A dichloro-S-triazine deriv. represented by the formula (where n≥2 and R is an n-valent org. group) is partially hydrolyzed with an about n×2W 4 equivalent aqueous soln. of NaCO 3, trisodium phosphate or the like at room temp. W about 50°C, and acetone used to dissolve the triazine is distilled out of the resulting filtrate under reduced pressure. An adequate amount of water is then added to the residue to prepare a gelatin hardening agent of a predetermined concn. the soln. may be evaporated to dryness to prepare a powdered hardening agent. When this agent is added to a silver halide emulsion, it is preferably added after the 2nd ripening by 5×10 -7W2.5×10 -3mol to 1g of dry gelatin. This agent shows high hardening speed, causes no post hardening, and exerts no unfavorable influence on photographic characteristics. COPYRIGHT: (C)1981,JPO&Japio
