摘要： PROBLEM TO BE SOLVED: To provide a method for simultaneously manufacturing a butadiene trimer, cyclododecatriene, useful as an industrial intermediate and a trans-1,4- polybutadiene, and a method for simply separating and purifying the trans-1,4- polybutadiene from a reaction solution containing these products. SOLUTION: Butadiene is allowed to react in the presence of a catalyst comprising a titanium compound and an organoaluminum compound to simultaneously give a trans-1,4-polybutadiene (TPB) and cyclododecatriene. In separating and purifying the TPB from a reaction solution obtained by allowing butadiene to react in the presence of the above catalyst, the TPB is precipitated and filtered to be separated from a still residue obtained by distilling off cyclododecatriene from the reaction solution.

摘要： PROBLEM TO BE SOLVED: To obtain the subject composition capable of providing a vulcanized product excellent in mechanical properties, elasticity, compression set and mold- releasing properties by mixing fluoroelastomers derived from bis-olefin monomers and having different properties. SOLUTION: This composition comprises a mixture of (A) 20-70 wt.% fluoroelastomer having >60 points of Mooney viscosity ML (1+10) at 121 deg.C, and 0.01-3 wt.% iodine content, with (B) 0-70 wt.% fluoroelastomer having 20-60 points of the Mooney viscosity, and 0.2-5 wt.% iodine content, and (C) 5-60 wt.% fluoroelastomer having 1-20 points of the Mooney viscosity, and 5-60 wt.% iodine content. Each of the components A to C has a structural unit derived from a bis-olefin monomer of the formula (R1 to R6 are each H or a 1-5C alkyl; Z is an (O-atom-containing, preferably partially fluorinated 1-18C alkylene, a cycloalkylene or the like).

摘要： PROBLEM TO BE SOLVED: To obtain a polymer dispersion useful for sludge coagulation by dissolving a product of acid hydrolysis of an N-vinylformamide/acrylonitrile copolymer in an aqueous sodium nitrate solution at high temperature and cooling the resulting solution under agitation to deposit microparticles. SOLUTION: A solution prepared by dissolving a product of acid hydrolysis of an N-vinylformamide/acrylonitrile copolymer in an aqueous sodium nitrate solution at temperature of as high as about 70 deg.C is cooled under agitation to a temperature of below about 30 deg.C to make a polymer dispersion containing the copolymer deposited in the form of microparticles. The sodium nitrate concentration of the aqueous sodium nitrate solution is in the range of 15-45wt.%. The stability of this dispersion can be improved by adding 0.1-1wt.%, based on the dispersion, sulfate thereto. It is desirable that the coagulation of this dispersion is prevented by adding 0.05-1wt.%, based on the dispersion, nonionic surfactant and 2-10wt.%, based on the dispersion, oily liquid (e.g. kerosene) thereto. This dispersion can be conveniently used and is useful in the coagulation of sewage sludge and as a dehydrating agent of a dehydrator.
