Abstract: Pharmaceutical compositions are provided for the treatment of disorders in a subject, such as hypertension, congestive heart failure, angina pectoris, lower urinary tract dysfunction and prostatic hypertrophy. The compositions when administered to a subject produce an .alpha.-adrenergic blocking action and contain as an active ingredient sulfamoyl-substituted phenethylamine derivatives, such as optically active 5-2-[ 2-(2-ethoxyphenoxy)ethylamino] -2-methylethyl-2-methoxybenzenesulfonamide 2-methoxybenzenesulfonamide, and a pharmaceutically acceptable carrier.

Abstract: A process for polymerizing 1,3-butadiene, comprising bring into contact a 1,2-polymerization catalyst consisting essentially of a soluble cobalt compound, an organic aluminum halide, an organic lithium compound, and carbon disulfide or phenyl isothiocyanate with 1,3-butadiene in a polymerization medium. The process can be applied particularly advantageously in the preparation of 1,2-polybutadiene, and the resultant 1,2-polybutadiene has a content of syndiotactic 1,2-structural units of not less than 90%, a melting point of 200.degree. C. to 220.degree. C., and an intrinsic viscosity [.eta.] of 1.2 to 7.

Abstract: A process for preparing a polyester fiber composite material having an excellent bonding property to rubber, a proper softness and a high resistance to fatigue, comprises the steps of first impregnating a polyester fiber material much as fabric, cord or thread, with a first treating liquid containing (A) a polyepoxide compound having two or more epoxy groups per molecule of the compound, (B) a blocked polyisocyanate compound, for example, an addition product of a polyisocyanate compound with a phenol, tertiary alcohol or aromatic secondary amine compound and (C) a rubber latex such as vinyl pyridine-styrene-butadiene terpolymer latex; first drying and heat treating the first impregnated material at a temperature of, preferably, 180.degree. C.
