    摘要： Elastomeric low density foamable compositions are described which are prepared from blends comprised of a major amount of a block copolymer comprised of an alkenyl aromatic and a conjugated diene and a minor amount of one or more other thermoplastic resins. Also described are such foamable compositions wherein such blends are comprised of a major amount of a triblock copolymer of the A-B-A type and a minor amount of polystyrene resin and/or polyphenylene ether resin. Also described are processes for preparing such low density foamable compositions and articles made therefrom.

    摘要： A process for producing expandable thermoplastic resin beads which comprises suspending in an aqueous medium interpolymer beads comprising a polyphenylene ether resin and a polymerized vinyl aromatic monomer such as styrene, polymerizing the vinyl aromatic monomer in the presence of a polymerization catalyst to interpolymerize the vinyl aromatic monomer with the polyphenylene ether and, optionally, adding a cross-linking agent, to form interpolymerized thermoplastic resin beads, and introducing a blowing agent under pressure into the thermoplastic resin beads. The resulting resin beads have excellent foamability and molding fusability, and a foamed shaped article having superior thermal stability can be prepared from these beads.

    摘要： This invention relates to an improved umbrella design, the cover of which is of a transparent, as opposed to opaque, material. The umbrella is in the shape of a dome-topped cylinder, the diameter of which approximates the width of an average person's shoulders. In one embodiment, the umbrella cover encompasses the torso of the user; in another, only the head and upper body. The umbrella further includes a DC motor and a wiper blade for wiping precipitation from that segment of the cover immediately in front of the user's face, to enhance vision.

    摘要： Thermoplastic compositions useful for preparation into shaped articles are provided which are based on mixtures of an aromatic polycarbonate resin, such as a poly(bisphenol-A carbonate) resin, and a copolymer of ethylene and acrylic or methacrylic acid. The ethylene copolymer can be an ionically crosslinked addition polymer (ionomer) as provided when the acid groups are neutralized with metal cations, or they can simply be random copolymers which are not ionically crosslinked. Articles prepared from the compositions are more resistant to undergoing delamination than counterpart compositions based on mixtures of polycarbonate and polyethylene.
