摘要：FIELD: chemistry.SUBSTANCE: invention relates to method of obtaining solution of gadolinium dialkylphosphate, which can be used in production of synthetic rubbers, cis-1,4-homopolymers and cis-1,4-copolymers of isoprene and butadiene. Claimed method consists in the following: first, mixed are: aliphatic and aromatic solvents with weight ratio 1:(4-5), dialkylphosphoric acid, activator in form of 20-40 wt % solution in water, and polyatomic alcohol, then, intensive mixing is switched on and gadolinium oxide is gradually added. After that mixture is heated to 80-90°C for 10-30 minutes.EFFECT: method is simple in technological aspect, makes it possible to considerably reduce synthesis time with obtaining solutions of gadolinium dialkylphosphates with low viscosity.3 cl, 8 ex
