摘要:
A film, laminated product, and other packaging materials are disclosed, each including an oxygen scavenger composition including mer units derived from a substituted alicyclic compound having non-aromatic, ethylenic functionality, mer units including an ionomeric group, and mer units of a di- or polyfunctional hydrocarbon compound. Certain oxygen scavenger compositions have been found to act as an oxygen scavenger under both ambient and refrigeration conditions, to be compatible with conventional film forming packaging materials, to inhibit undesirable oligomer formation and oxidation by-product formation, and to be readily formable and processable using conventional film forming equipment.

摘要:
Sulfonated aliphatic-aromatic copolyesters and articles made therefrom, and processes for producing the sulfonated aliphatic-aromatic copolyesters and articles are provided. Articles that can be made from the sulfonated aliphatic-aromatic copolyesters include films, coatings and laminates. Some of the compositions and articles are biocompostable. The films can further be used to form shaped articles such as sheets, food packaging such as sandwich wraps, thermoformed containers, and coatings for, for example, films and other substrates. The sulfonated aliphatic-aromatic copolyesters are derived from copolyesters produced from aliphatic-aromatic copolyesters formed from an aromatic dicarboxylic acid component, an aliphatic dicarboxylic acid component, a first glycol component consisting of 1,4-butanediol, a second glycol component, and optionally, a polyfunctional branching agent.

The invention provides a process that can be used for producing a bis-glycolate ester of 5-sulfo isophthalate metal salt. The process comprises contacting a 5-sulfo isophthalate a metal salt or a dialkyl ester of 5-sulfo isophthalate metal salt, in the presence of a catalyst, with a glycol. The catalyst comprises (1) a titanium compound, a solubility promoter, a phosphorus source, and optionally a solvent, (2) a titanium compound, a complexing agent, a phosphorus source, and optionally a solvent, a sulfonic acid, or combinations thereof, or (3) combinations of (1) and (2). The solubility promoter can be selected from the group consisting of ortho silicates, ortho zirconates and combinations thereof. The phosphorus source is selected from the group consisting of a phosphonic acid, a phosphinic acid, a phosphine, and combinations of two or more thereof. The complexing agent can be selected from the group consisting of hydroxycarboxylic acids, aminocarboxylic acids, and combinations thereof. The invention also provides a process that can be used for producing a cationic dyeable polyalkylene terephthalate. The process comprises contacting a mixture, in the presence of an esterification or transesterification catalyst, with a glycol in which the mixture comprises the bis-glycolate ester of 5-sulfo isophthalate metal salt produced by the process disclosed above and either a terephthalate acid or a dialkyl terephthalate.
