A. Krogulecki et J. Mosiomosiewski, MONOURETHANES AND DIURETHANES OF ALKYLENE GLYCOLS AS PLASTIFIERS OF AMINO RESINS, Przemysl Chemiczny, 73(11), 1994, pp. 433-434
The influence was tested of the addition of mono- and diurethanes of a
lkylene glycols on elasticity of amino resins. Materials of very high
elasticity were obtained when -NH2 groups of mono- and diurethanes of
diethylene glycol substituted 6,1 mol % of urea -NH2 groups. Similar p
lastifying properties were obtained when urethanes of dipropylene and
butylene glycols were applied.
