FIELD: organic chemistry, production of building materials. SUBSTANCE: proposed method resides in reacting organic polyisocyanates with modified castor oil in presence of catalyst and foaming agent and, optionally, in presence of purposive additives. Inventive novelty of proposed method resides in that said modified castor oil is represented by product resulting from reacting castor oil with amines and/or hydroxyl compounds having hydroxyl number 200-500, water being used as foaming agent. EFFECT: useful method producing cheap and good-quality foam plastic for use as building and packing material. |
