✦ Synopsis

Polyamidhides with elastic properties, suitable as foils, fibers, and varnishes, are prepared by polycondensation of diamides and water) in water. [DOS 2423 881 ; Monsanto Co., St. Louis (USA)] [PR 259 IE-D] Low-molecular polymers containing terminal hydroxy groups, suitable for the preparation of polyurethanes, are obtained by the polymerization of conjugated dienes with hydrogen peroxide as catalyst in a liquid multiphase reaction system. The preferred reaction medium is a mixture of isopropanol and water containing 70-88'x of the alcohol. [DOS 2326677; Atlantic Richfield Co., Los Angeles (USA)] [PR 261 IE-D] Bis(hydroxymethy1)methylphosphane oxide (2 ) is formed in an exothermic reaction by rearrangement of tris(hydr0xymethof type ( I , J or (2) with, e.g. benzophenonetetracarboxylic dianhydride in e. g*, rnethylpyrrolidone.
