    摘要: Polyethers having improved barrier to oxygen are normally solid, thermoplastic polyethers having aromatic ether repeating units in their backbones and pendent hydroxyl moieties and pendent amido, N-substituted amido and/or hydroxyalkyl moieties. Such polyethers are prepared by reacting diglycidyl ethers of dihydric aromatic compounds such as diglycidyl ether of bisphenol A with dihydric phenols having pendent amido, N-substituted amido and/or hydroxyalkyl moieties such as 2,2-bis(4-hydroxyphenyl)acetamide and 3,5-dihydroxybenzamide.

    摘要: Polyhydroxyethers formed by reacting a diglycidyl ether of biphenol, such as diglycidyl ethers of bisphenol-A, and a dihydroxybiphenyl, such as dihydroxybiphenyl, tetramethyldihydroxybiphenyl, and tetrabromotetramethyldihydroxybiphenyl, exhibit high heat distortion temperatures. These compositions could find utility in extruded films, packaging and coatings.

    摘要: The invention, in one aspect, is a copolymer comprising amorphous polyamide hard segments, which contain 1-methyl-2,4-phenylene, 1-methyl-2,6-phenylene, or mixtures thereof structure units. The structure characteristics of 1-methyl-2,4-phenylene, 1-methyl-2,6-phenylene, or mixtures thereof render the hard segments having glass transition temperatures below 200° C. while maintaining physical properties required for making molded articles.
