Title compd. was prepd. by the hydrogenation of 2-cyanoethoxy-polyoxyalkylene (I) in the presence of Ni catalyst. I was obtained by cyanoethylation of polyoxyalkylene (M.W. 7300) having OH group. Thus, 100 g bis (2-cyanoethoxy)-polyoxyethylene (M.W. 7,650, OH 0.05 meq/g, cyano 0.256 meq/g) was hydro...
