  • Process for the preparation of cellular or noncellular plastics from at least two components which react with one another
    Patent number: 4649162
    Abstract: The invention relates to a process for the preparation of cellular or noncellular plastics, preferably polyurethane coatings, by reacting at least two components with one another, preferably organic polyisocyanates and polyhydroxyl compounds, by feeding the components into a mixing zone separately, and mixing them together and then discharging the reaction mixture from the mixing zone, while adding air heated to a temperature of 100.degree. to 1200.degree. C. to the reaction mixture as it emerges from the mixing zone.
