  • Patent number: 10767005
    Abstract: Bibenzoate copolyesters are based on (4,4?-biphenyl dicarboxylic acid-co-3,4?-biphenyl dicarboxylic acid) as the diacid component, and on an alicyclic diol compound such as 1,4-cyclohexanedimethanol as a portion of the diol component.

  • Publication number: 20200262971
    Abstract: Copolyesters are based on a diacid component containing terephthalate and 4,4?-biphenyl dicarboxylate or 3,4?-biphenyl dicarboxylate, and a diol component containing an alkylene diol, e.g., ethylene glycol or NPG, and an alicyclic polyhydroxyl compound, e.g., CHDM. The copolyesters may have a glass transition temperature more than 100° C. and mechanical, thermal and/or barrier characteristics at least comparable to some commercially available copolyesters. A method to control the morphology and properties of a copolyester involves contacting diacid and diol components in the presence of a catalyst, selecting proportions of terephthalic and 4,4?-biphenyl dicarboxylic or 3,4?-biphenyl dicarboxylic acids or ester producing equivalents thereof in the diacid component, and selecting the alkylene diol and proportions of the CHDM (or other alicyclic polyhydroxyl compound) and the alkylene diol in the diol component, to obtain the desired morphology and other properties.

  • Patent number: 5446106
    Abstract: Copolymers are produced when a 4-vinyl-1,3 dioxolane monomer is copolymerized with an imidized maleic anhydride (for example, maleimide) monomer in the presence of a free radical initiator. Alternatively, a maleamic acid or maleimide functionality may be introduced into a copolymer containing a 4-vinyl-1,3 dioxolane and maleic anhydride by introducing a primary amine into the reaction mixture. Also, the dioxolane reactant may be introduced into the polymer by reacting 3,4-epoxy-1-butene in a ketone reaction solvent. The structure and composition of the product copolymer are controlled by both the sequence and conditions of the reaction. Products of the present invention can be cast as clear films and can also be used as reactive polymers.

  • Patent number: 5283008
    Abstract: There is disclosed a composite of 1) a polymer containing repeating units derived from a vinyl carboxylic ester having at least one organo terminated poly(alkylene oxide) side chain with the proviso that the poly(alkylene oxide) is present in an amount greater than 35 mole percent of the total of all backbone monomer units and alkylene oxide units in the polymer and 2) a metal oxide wherein the metal oxide comprises between about 1 and about 60 percent by weight of the composite. The composites can be made by a process comprising the steps of:combining the described polymer and a metal oxide precursor in a solvent solution;casting or coating the resulting solution onto a substrate;curing the resulting sample to form acomposite of the polymer and the metal oxide. Optionally, the composite can be removed from the substrate to form a transparent free standing film. These composites have a variety of desirable properties.
