    摘要： Disclosed herein are adhesives comprising a copolymer comprising at least 80 wt % of units derived from propylene and from about 1 to about 20 wt % of units derived from at least one C6 to C10 alpha-olefin. The copolymer has a molecular weight of less than 100,000 and a heat of fusion between about 10 and about 70 J/g. An adhesive containing the copolymer preferably exhibits at least 50% fiber tear at −18° C. and at least 50% fiber tear at +25° C. using Inland paper board as a substrate; a viscosity of less than 50,000 mPa sec at 190° C., a set time of less than 4 seconds and a toughness of at least 3.4 megajoule/m3.

    摘要： Terephthalic acid (TPA) is recovered from used polyethylene terephthalate beverage containers by reacting comminuted containers in a reaction zone with an aqueous medium containing ammonium hydroxide at elevated temperatures and pressures to form a water soluble diammonium salt of TPA, separating any undissolved solids from the reaction product, acidifying the remaining reaction product to liberate TPA, and separating the precipitated TPA. A portion of the liquid remaining after separation of TPA can be mixed with lime or slaked lime, the resulting mixture treated in an ammonia stripper to remove ammonia therefrom and the ammonia overheads from the stripper blended with another portion of the liquid remaining after separation of TPA to form a stream containing ammonium hydroxide which is recycled to the reaction zone. Ethylene glycol can be recovered from the bottoms from the ammonia stripper by distillation.
