The known method of pits / cages of asorco-containing hydrohepimers is carried out by radically} copolymerisation of meta phasic effects of higher alcohols with aifeneschminoethyl methacryle atom.

 The proposed method differs from the known one in that the methacrylate ester of N-ethanol monoethylaniline is used as the nitrogen-containing comonomer.

This difference allows for an expansion in the range of polymers that can be used to produce effective fuel additives.

Initiation of cc polymerization can be carried out with the help of r-from {tscheni or real inipiatora.

As methacrylic esters of higher fatty alcohols, esters of both individual alcohols (C to C 12) and mixtures of C alcohols are used. Styrene can also be added to the initial monomer mixture. The co-pimerisation is carried out in bulk or in the middle of the solvent.

Benzene hydroxyperoxide or azodinitrile diisobutyric acid are used as material inters.

From the abovementioned compounds, under the action of γ-radiation, is carried out at a temperature of 30 ° C for the reaction mixture (source temperature is about 45 ° C).

Example 1. In a flask, you are placed 10 g of methacrylate N-ethanol monoethane and 4O g of methyl methacrylate and subjected to a mixture of y-sb scientifically (

5 -1O b happy) at a source temperature of 45C.

The output of the copolymer 50 g, molecular weight 94OOO. Nitrogen content of 1.2%

Example 2. In a count put 7 g of mefacrylate N-ethanol monoethyl I lin, 63 g octyl methacrylate, ZO g -goduol. The mixture is subjected to γ-irradiation (the dose of teaching 6.

The output of the copolymer is 100%. Molecular weight (viscometric) 50OOO. The nitrogen content in the copolymer 0,42%.

Example 3; In a flask, 7 g of methacrylate N-ethanol monoethaniline, 42 g of decipitacrylate, 21 g of styrene, ZO g of toluene are placed. The mixture is subjected to r-radiation (dose of 6-10 rad). The output of the copolymer is 100%. The nitrogen content is 0.42%.

Example4. The flask is placed 23.3 g of methacrylate N-ethano shonoethylaniline, 198 g of octylmethacrylate and 2.2 g (1%) of bischol esteroxide isopr sylbenzene. The mixture is heated at 12 ° 125 ° C for 7 hours. The yield of co-polymer is 1OO%. The nitrogen content is 0.63. Molecules of pvsoy weight 6416O.

Example 5: 5.5 g of methacrylate N-ethanoloyl Bvioioethaniline, 35 g of singlemethacrylate, 10 g of styrene, 21 g of toluene and 0, 5 g (1%) g of dsherekisi izitrocylbe ash. The mixture is maintained at 12O-125 ° C for.

Output c (Ylimera 1OO%. Molecular weight 592OO. Nitrogen content 0.42%

Based on those obtained from Ja1olv 4er (you can get effective fuel additives.

Claims (1)

high esters of higher fatty alcohols with a nitrogen-containing unsaturated compound, with the fact that, in order to expand the range of polymeric materials, methacrylic ester of N-ethanol monoethylaniline is used as a nitrogen-containing compound.
