    摘要: A thermoplastic molding composition having a high neat deflection temperature but a relatively low melt extrusion temperature is formed by blending a polyetherimide with about 35 to about 80 weight percent of a copolyester of terephthalic and/or isophthalic acid and a glycol component comprising ethylene glycol and up to about 60 mol percent of 1,4-cyclohexanedimethanol. The blend also has a high flexural modulus and can be used to form plastic articles that can be molded at moderate temperatures but retain flexural strength at elevated temperatures. Certain compositions of the invention are clear, single phase solid solutions.

    摘要: The hot-melt adhesives of the present invention comprise a blend of poly(propylene-co-higher 1-olefin), tackifying resin and crystalline propylene containing polymer. These hot-melt adhesive compositions have a novel combination of properties including strong T-peel and lap shear bonds to both low- and high-density polyethylene with excellent creep resistance at ambient temperatures. Therefore, these new hot-melt adhesives are excellent adhesives for applications such as sealing high-density polyethylene grocery bags and low-density shipping bags.
