FIELD: chemistry. ^ SUBSTANCE: present invention pertains to antistatic media, which prevent accumulation of static electricity, arising on the surface of textile materials, carpets, on artificial and natural fur. The aim of the invention is to develop a method of obtaining antistatic media, which allows for increasing antistatic effect, increase thermal stability and moisture resistance. Proposal is given of a method of obtaining an antistatic medium through radical co-polymerisation of N,N-dimethyl-N,N-diallylammonium chloride and methacrylic methylester in a period of 6-10 hours at 40-60C in mass ratio of co-monomers N,N-dimethyl-N,N-diallylammonium chloride and methacrylic methylester of 1:0.005-3.0, with addition of ammonium persulphate in its mass ratio to the mixture of co-monomers N,N-dimethyl-N,N-diallylammonium chloride and methacrylic methylester of 1:250-2000 with subsequent addition of dimethyl sulfoxide in quantity, 3.4 times more than the total mass of N,N-dimethyl-N,N-diallylammonium chloride, methacrylic methylester and ammonium persulphate. Compared to the prototype, antistatic effect increases 3-5 fold, thermal stability and moisture resistance increase 5-11 fold. ^ EFFECT: development of a method of obtaining antistatic media, which allows for increasing antistatic effect, increase thermal stability and moisture resistance. ^ 1 cl, 1 tbl, 4 ex |
