摘要:
Hydrophilic curable resin composition for preparing hydrophilic resin coating films on articles, which contains, as the resinous component, a polyether ester consisting of 60 to 10 % by weight of non-hydrophilic portion and 40 to 90 % by weight of a hydrophilic polyether portion forming the main chain of the molecule, and said non-hydrophilic portion containing 3 or more equivalents of polymerizable ethylenically unsaturated bond component per mole of said polyether ester based on the average molecular weight, and the coating films formed therefrom, which have water resistance and other excellent properties.
摘要:
A new process for the manufacture of low molecular reactive surface-active agents from carbamides, which comprises reacting a monomethylol compound of a carbamide, which is optionally etherified with a monohydric alcohol with 4 to 7 carbon atoms, with a hydrophobic or hydrophilic hydroxy compound thereafter introducing a second methylol group into the ether compound thus obtained by means of formaldehyde or a formaldehyde donor, and etherifying this methylol group with a hydrophilic or hydrophobic hydroxy compound in such a way that the end product contains at least one hydrophobic and one hydrophilic group.

Aqueous liquid detergent compositions that remain clear and liquid over a wide range of temperatures are provided comprising an ampholytic betaine-type detergent, a nonionic surfactant, and a complexing agent. The ampholytic betaines that are employed in the liquid detergent compositions of the invention have the formula:
wherein: 1. R represents an aliphatic or cycloaliphatic group having from about six to about 22 carbon atoms or an aromatic group linked to the oxygen of the OR group via a carbon of the aromatic nucleus and having from one to six alkyl groups totalling from about four to about 18 carbon atoms in the alkyl groups, each alkyl group having from one to about 18 carbon atoms; 2. R1 and R2 are selected from the group consisting of alkyl groups having from one to about three carbon atoms; 3. N1, N2 AND N3 REPRESENT THE NUMBER OF CARBON ATOMS IN EACH UNIT, AND ARE WITHIN THE RANGE FROM ABOUT 2 TO ABOUT 4; 4. M1, M2 AND M3 REPRESENT THE NUMBER OF OXYALKYLENE UNITS, AND ARE WITHIN THE RANGE FROM 0 TO ABOUT 10; AND 5. N4 REPRESENTS THE NUMBER OF CARBON ATOMS IN THE UNIT, AND IS WITHIN THE RANGE FROM 1 TO ABOUT 4.
摘要:
Perfluorocyclocarbons and emulsions containing emulsified particles of these perfluorocarbons are useful is supporting life as intravascular oxygen and carbon dioxide transport agents. Stable emulsions of perfluorocarbocyclic derivatives are prepared for use as artificial bloods and perfusates for organs. Intravenously infused emulsions containing perfluorocyclocarbons such as perfluoro(methylcyclohexane), perfluoro(1,3dimethylcyclohexane), perfluoro(decahydronaphthalene), perfluoro(decahydro-1-methylnaphthalene), perfluoro(decahydrodimethylnaphthalene), and the like, serve as intravascular oxygen and carbon dioxide transport agents. Fluorocarbon liquids are also useful as an external respiration media for transporting oxygen-carbon dioxide necessary to support intravascular respiration. Perfluorocyclocarbons have been found after intravenous emulsion infusion as artificial bloods to collect in the reticuloendothelial system (RES) of the amimal body. However, it has also been found that perfluorocyclocarbon compounds leave the RES of the animal body and certain of these compounds, e.g., perfluoro(decahydronaphthalene), leave the RES at a much faster rate than others. Furthermore, after the intravenously infused perfluorocyclocarbon emulsions function as artificial bloods, the perfluorocyclocarbons have the capability of leaving the animal body through the tissue, e.g., the lungs and skin.
摘要:
Photographic element comprising a support and a light-sensitive silver halide emulsion layer is described. The element includes in a water-permeable layer, which may be the silver halide emulsion layer, a hydrophilic colloid binder and as a surfaceactive agent a monoether or monoester of a polyglycol having oxyethylene units and oxypropylene units in a ratio of at least 2 oxyethylene units to 1 oxypropylene units, the terminal hydroxyl group of said polyglycol monoether or monoester being carboxyalkylated and the carboxyl group being in acid or salt form. The photographic elements do not exhibit hydrophobic inclusions which lead to repellency spots or comets and, additionally, are resistant to yellowing upon development.
