Pagination or Media Count:
The object of the invention is a method of obtaining a foam plastic on the basis of unsaturated polyestermaleate resins, siisocyanates, water, a catalyst, and an emulsifier, by mixing the original components with subsequent foaming and hardening of the composition. To increase the stability of the foam and improve the sanitary conditions of the work, unsaturated polyestermaleate resins are used in the form of solutions of them in nonvolatile di- and polyester-acrylates. Unsaturated polyester maleates that contain chlorine may be used to give the foam plastic the properties of self-attenuation. Author
