It was found that the dimethylsilylamine polymer formed by reaction between dimethyldichlorosilane and ethylenediamine will react with anhydrous beryllium chloride to produce a coordination polymer which contains sufficient beryllium to coordinate up to 72 of the nitrogen atoms in the polymer, assuming that beryllium is four-coordinate. Reaction of the dimethylsilylamine polymer with aluminum chloride altered the physical properties of the polymer, but reaction with aluminum fluoride produced no change. The silylamine polymer formed by reaction between diphenyldichlorosilane and ethylenediamine has interesting adhesive properties and good resistance to hydrolysis. It shows only a slight tendency to react with beryllium chloride. A resinous polymeric amide was prepared by reaction between ethylene-diamine and fumaric acid. Coordination attempts with this polymer were unsuccessful, but coordination studies with polymers containing double bonds merit further attention. Author
