A method for producing a modified butadiene-styrene film-forming agent by reacting a butadiene-styrene film-forming agent with an unsaturated compound at 90-120 s, characterized in that, in order to reduce the toxicity of the target product, reduce the time of the process and improve the properties of the surface-based dressing gown. compounds use 5.7–9.1 wt.% of the film-forming bottom residues of the isoprene purification process, which is a resin with a softening temperature of 30-60 ° C and soda Neighboring in its composition up to 35-70 wt.% fulvena and its polymerization products. |
