    摘要: A new process has been developed for separating the water and acetic acid present in the aqueous phase contained in cellulose acetate flakes precipitated from esterification solutions of cellulose. The process includes the step of simultaneously extracting water and acetic acid from the aqueous phase with supercritical carbon dioxide until the content of water and acetic acid in the flakes is substantially reduced.

    摘要: A composition of polyester resins comprising diblock copolymers formed of two different polyester blocks joined by a bifunctional radical deriving from a dianhydride of a tetracarboxylic acid. The compositions are prepared by a reaction in the solid state of two different polyesters in the presence of a dianhydride of a tetracarboxylic acid.

    摘要: An oxygen scavenging composition is set forth in which the composition contains a protic solvent hydrolysable halogen compound which is deposited upon oxidizable metal particles, contacting the metal with an essentially moisture free liquid containing the protic solvent hydrolysable halogen compound and then evaporating, if necessary, any remaining solvent from the solid. Also set forth are walls of containers and preforms which contain this composition.

    摘要: The present invention relates to a process of recovering aromatic dicarboxylic acids with low metal contaminants from manufactured articles, such as beverage bottles, fibers and films, comprising aromatic polyesters, whether or not those articles are contaminated with PVC or chlorinated compounds, or from waste from processing of these polyesters. In particular, the invention relates to the recovery of terephthalic acid, isophthalic acid and 2,6-naphthalene dicarboxylic acid from bottles for recycling which are made of PET, PEN or aromatic polyester copolymers.
