ABSTRACT:
Thermally stable water soluble resins are prepared in a multistep process by reacting the waste solids from the mother liquor waste stream of a melamine manufacturing plant with an aldehyde and a sulfonating agent under controlled conditions of pH and temperature. The resin compositions are useful, for example, as superplasticizing agents for concrete mixtures, as mud drilling additives, and in the paper and textile industry. The process not only provides useful resin compositions, but also recovers solid wastes which are considered to be a major contributor to the pollution problems of melamine manufacturing plants.
