Abstract

Low-mol. wt. polymers of conjugated dienes, with terminal OH gps., are prepd. by reacting a conjugated diene with an aq. soln. of H2O2, as catalyst in is not 1 aliphatic alcohol satd. with water, in a system contg. is not 2 phases; the polymer is sepd. from the reaction medium and washed to remove residual alcohol; after the reaction, the water-alcohol mixt. is distilled off as an azeotrope. The hydroxylated polymers can be reacted diisocyanates to yield polyurethanes. Reaction with di-acids or their halides also yields elastomers and foams.
