Abstract: PURPOSE:To provide the titled dispersing agent containing a specific amount of monoalkylphosphoric acid having straight-chain alkyl group, capable of keeping the polymerizing system in stable state and enabling the production of fine granular polymer free from powdery polymer in high efficiency. CONSTITUTION:A dispersing agent containing >=80mol% monoalkylphosphoric acid having 12-24C straight-chain alkyl group is used as a dispersing agent for the reverse-phase suspension polymerization performed by adding an aqueous solution of a water-soluble ethylenic unsaturated monomer to a hydrophobic solvent inert to the polymerization reaction (e.g. n-hexane, benzene, toluene, etc.). The amount of the solvent is preferably 0.05-5.0wt% of the monomer. EFFECT:It is supposed that the dispersing agent is regularly arranged at the oil/water interface owing to the balance between the hydrogen bond of the phosphoric acid group and the hydrophobic straight-chain alkyl group to stabilize the interface and accordingly the reverse-phase suspension polymerization system can be maintained stably.

Abstract: PURPOSE:To produce a polyalpha,beta-unsaturated nitrile with a narrow molecular- weight distribution under relatively mild conditions by polymerizing an alpha,beta-unsaturated nitrile in the presence of an aluminum porphyrin complex combined with a Lewis base. CONSTITUTION:An alpha,beta-unsaturated nitrile (e.g., methacrylonitrile or cinnamonitrile) is polymerized using an aluminum porphyrin complex as an initiator in the presence of a Lewis base (e.g., methylamine, 1,2,3-triazole or ethylphosphine), preferably at a mole ratio of 100-0.1 time based on the amount of the above-mentioned complex. A compound of the formula (R1 and R2 are H or 1-10C hydrocarbon; R3 is H or 1-20C hydrocarbon which may have functional groups such as halogen, alkoxy or ester) is preferable as the aluminum porphyrin complex.
