Abstract: An antifoaming agent for fermentation, which comprises (A) a reaction product obtained by the addition polymerization of 50 to 250 moles of ethylene oxide and propylene oxide (the molar ratio of ethylene oxide to propylene oxide = 1:1 to 1:4 ) to 1 mole of a mixture composed of an oil or fat and a polyhydric alcohol containing at least three hydroxyl groups; and (B) a fatty acid, an alcohol, a polyoxyalkylene polyhydric alcohol ether, a polyoxyalkylene alkyl ether, a polyoxyalkylene fatty acid ester, a polyoxyalkylene alkyl ether fatty acid ester and/or a polyoxyalkylene polymer. The above antifoaming agent has both foam-breaking effects and foam-inhibiting effects so that it has excellent antifoaming effects and does not adversely affect the fermentation production.

Abstract: A method for producing a formed product of deproteinized natural rubber latex capable of reducing a content of an allergen in a natural rubber latex material to a level sufficient to keep the latex from being harmful to the human body without decreasing yields of the product and deteriorating formability of the latex. In the method, cleaning removal of a non-rubber content is carried out after each of protein decomposition, prevulcanization and forming. An aqueous alkali solution, ammonia, water containing free chlorine in an amount of 0.005 to 0.02 by weight or alcohol-water mixed liquid containing alcohol in an amount of to 80% by weight is used as cleaning liquid for the cleaning removal. The method is suitably applied to production of a natural rubber product such as a rubber glove, a condom, a catheter, a foam rubber material and the like.

An aqueous alkali solution, ammonia, water containing free chlorine in an amount of 0.005 to 0.02% by weight or alcohol-water mixed liquid containing alcohol in an amount of 5 to 80% by weight is used as cleaning liquid for the cleaning removal. The method is suitably applied to production of a natural rubber product such as a rubber glove, a condom, a catheter, a foam rubber material and the like.

Abstract: A DEPOLYMERIZED NATURAL RUBBER IS DISCLOSED, WHICH IS A LIQUID RUBBER HAVING A NUMBER-AVERAGE MOLECULAR WEIGHT OF FROM 2,000 TO 50,000 OBTAINED BY THE DEPOLYMERIZATION OF A DEPROTEINIZED NATURAL RUBBER. A PROCESS FOR THE PREPARATION OF A DEPOLYMERIZED NATURAL RUBBER IS ALSO DISCLOSED, WHICH COMPRISES DISSOLVING A DEPROTEINIZED NATURAL RUBBER INTO AN ORGANIC SOLVENT SO AS TO GIVE A CONCENTRATION OF FROM 1 TO 30BY WEIGHT AND THEN CARRYING OUT AIR OXIDATION OF THE RESULTING SOLUTION IN THE PRESENCE OF A METALLIC CATALYST. THE DEPOLYMERIZED NATURAL RUBBER CAN PROVIDE THE SAME PHYSICAL PROPERTIES AS ORDINARY VULCANIZED RUBBERS, EXHIBITS NO ODOR OR COLOR CHARACTERISTIC TO NATURAL RUBBERS AND CAUSES NO IMMEDIATE ALLERGY INDUCED BY PROTEIN.

Abstract: Described is a process for the production of depolymerized natural rubber, which makes it possible to obtain, at high reaction efficiency, of depolymerized natural rubber in the liquid form and having a narrow molecular weight distribution; and also a process for the production of depolymerized natural rubber which is free from odor or coloring peculiar to natural rubber and is also free from the danger of immediate allergy derived from protein. The process according to the present invention comprises adding a carbonyl compound to a natural rubber latex, and then subjecting the resulting natural rubber to air oxidation in the presence of a radical forming agent or adding a carbonyl compound to the latex of deproteinized natural rubber and then subjecting the deproteinized natural rubber to air oxidation optionally in the presence of a radical forming agent.

Abstract: A depolymerized natural rubber is disclosed, which is a liquid rubber having a number-average molecular weight of from 2,000 to 50,000 obtained by the depolymerization of a deproteinized natural rubber. A process for the preparation of a depolymerized natural rubber is also disclosed, which comprises dissolving a deproteinized natural rubber into an organic solvent so as to give a concentration of from 1 to 30 % by weight and then carrying out air oxidation of the resulting solution in the presence of a metallic catalyst. The depolymerized natural rubber can provide the same physical properties as ordinary vulcanized rubbers, exhibits no odor or color characteristic to natural rubbers and causes no immediate allergy induced by protein.
