    摘要: In a composition for producing polyurethane foam which comprises an organic polyisocynate compound, a compound having at least one active hydrogen atom in the molecule, a foaming agent and a catalyst as essential components, an aminoalkylsilane represented by the following general formula is contained: ##STR1## wherein n is 1 or 2, and R.sub.1 to R.sub.5 are alkyl groups. By use of such a catalyst polyurethane foam having a even color distribution and excellent mechanical properties is produced.

    摘要: In a dynamoelectric machine having a stator assembly of coil windings and a core, a heat-dissipating, uninflammable, electro-insulative housing encapsulates the coil windings and the core. The housing is made of a cured molded article or material formed of a resin-filler composition which comprises a liquid unsaturated polyester resin, a finely divided calcium carbonate powder, an inorganic mineral particulate having a particle size larger than that of the calcium carbonate powder, a chopped glass fiber and an aluminum hydroxide powder, wherein the ratio by weight of the calcium carbonate to the mineral particulate is 0.3 to 4, the ratio of the weight of glass fiber to the total weight of the composition is 0.05 to 0.25, the ratio of the weight of the polyester resin to the total weight of the composition is 0.1 to 0.4, the weight ratio of the calcium carbonate powder, the mineral particulate and the glass fiber to the total weight of the composition is 0.15 to 0.80, and the weight ratio of the aluminum hydroxide powder to the total weight of the composition is 0.1 to 0.6.
