    Abstract: The present invention provides a tetrahydrofuran purge stream treatment process, and a process for manufacturing polyether glycol comprising same. The process for treating a tetrahydrofuran stream purged from a polyether glycol manufacturing process comprises steps of neutralizing acidic substances in a tetrahydrofuran stream purged from the polyether glycol manufacturing process with an aqueous base solution, feeding the neutralized effluent to an azeotropic distillation column, and distilling tetrahydrofuran and water overhead from the azeotropic distillation column. The process can further comprise a step of disposing of the neutralized salts and excess base in the aqueous bottoms stream from the azeotropic distillation column. The process can further comprise steps of recovering THF from the overhead of the azeotropic distillation column, and recycling the recovered THF to a polyether glycol manufacturing process.

    Abstract: The present invention concerns a reactive carrier that forms no by-products during melt injection of polymer into articles such as sheets, films, fibers and containers. The reactive carrier is used to mix additives into the polymer resin. More particularly, the invention relates to the use of one or more cyclic anhydrides or substituted cyclic anhydrides as the reactive carrier. The polymer can be polyester or polyamide. Suitable cyclic anhydrides are those with a melt point of less than the polyester or polyamide, preferably less than about 160 °C, and more preferably less than about 125 °C. Most preferable are cyclic anhydrides with a melt point less than about 100 °C and especially suitable are those that are liquid at room temperature (25 °C). The cyclic anhydride may be selected from the group of succinic anhydride, substituted succinic anhydride, glutaric anhydride, substituted glutaric anhydride, phthalic anhydride, substituted phthalic anhydride, maleic anhydride, substituted maleic anhydride, or mixtures of two or more of these.

    Abstract: A device includes a substrate (20), a first adhesive (33), and a carrier layer (50). The substrate has a finish layer (40). The substrate has sufficient flexibility to allow manual rolling and to allow manual unrolling without damage. The substrate has a plurality of discontinuous segments (70A, 70B, 70C). The first adhesive is disposed on an opposing side of the finish layer. The first adhesive is configured for pressure sensitive bonding. The first adhesive has a release characteristic such that the substrate can be bonded and disbonded relative to a substantially planar surface and incur no damage. The carrier layer (50) is bonded to the finish layer by a second adhesive (55). The second adhesive is configured to retain the plurality of discontinuous segments in fixed spatial alignment. The second adhesive is configured to cleanly disbond from the finish layer by manual peeling.
