Abstract

Process for obtaining a polyurethane reaction product characterized by mixing in the liquid state (1) a polyether glycol polymer terminated in hydroxyl, of molecular weight of at least 600, obtained by condensation of an alkylene oxide of 2 to 4 carbon atoms at least 20% of whose alkylene oxide has more than 2 carbon atoms, with 0.01 to 10 mols%, on the alkylene oxide, of a polyhydric alcohol of less than 7 carbon atoms and with 3 to 6 groups primary hydroxyl, and (2), a molar amount of an organic diisocyanate at least equal to said polyether glycol; reacting the mixture until a second polymer with a chain length substantially greater than that of said polyether glycol polymer is formed.
