摘要:
An image-bearing article comprising a film layer bearing an image and a polymeric interlayer sheet comprising an ionomer copolymer of an alpha-olefin and about 15 to about 30 wt % of an alpha, beta-ethylenically unsaturated carboxylic acid based on the total weight of the ionomer copolymer, wherein about 5 to about 90 percent of the carboxylic acids are neutralized with one or more metal ions. In addition, a process of preparing an image-bearing article comprising an image-bearing film layer and an ionomer interlayer sheet: (a) providing a film layer; (b) printing an image on the film layer so as to produce an image-bearing film layer containing an image-bearing side; and (c) laminating an ionomer interlayer sheet to the image-bearing side of the image-bearing film layer. Preferably the film layer is coated on the image-bearing side and over the image with an adhesion promoter.

摘要:
Aliphatic-aromatic polyetherester compositions, articles made from the aliphatic-aromatic polyetherester compositions, and processes for producing the aliphatic-aromatic polyetherester compositions and articles are provided. Articles that can be made from the aliphatic-aromatic polyetherester compositions 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 aliphatic-aromatic polyetheresters are based on copolyesters produced from a mixture of aromatic dicarboxylic acids, aliphatic dicarboxylic acids, poly(alkyene ether) glycols, and glycols.

The present invention provides a process to produce isosorbide-containing polyesters. The process allows for higher isosorbide incorporation than previously found while maintaining high polymeric molecular weights.
摘要:
A copolyester having an inherent viscosity of equal to or greater than about 0.3 formed from about 20 to about 60 mole percent based on the amount of aromatic dicarboxylic acid of one or more of isophthalic dicarboxylic acid or an alkyl diester thereof, about 40 to about 80 mole percent based on the amount of aromatic dicarboxylic acid of one or more of terephthalic acid or 2,6-naphthalene dicarboxylic acid or an alkyl diester thereof, about 10 to about 60 mole based on the total amount of dicarboxylic acids of one or more aliphatic dicarboxylic acids or an alkyl diester, about 0.1 to about 5 mole percent based on the moles of total dicarboxylic acid of one or more alkali or alkaline earth metal salts of 5-sulfoisophthalic dicarboxylic acid or an alkyl diester thereof, about 90 to 100 mole percent based on the total amount of glycols of one or more aliphatic glycols, and 0 to about 10 mole percent based on the total amount of glycols of one or more of di(ethylene glycol) and tri(ethylene glycol). The copolyesters are useful to form films and coatings.
摘要:
The present invention provides processes for producing certain very low inherent viscosity polyesters. Also provided are the low inherent viscosity polyesters in discrete particulate form, and processes for producing the particulate polyesters. The discrete particulate materials are desirable for use in further processes.
摘要:
A sulfonated copolyester of the reaction product of: (a) one or more aromatic dicarboxylic acids or an ester thereof; (b) one or more aliphatic dicarboxylic acids or an ester thereof; (c) one or more sulfonated compound; and (d) isosorbide. The polyesters are useful to form articles of increased biodegradability.
