  • Patent number: 10265745
    Abstract: A seamless, embossed or cast substrate is formed using a seamless sleeve having a seamless surface relief formed thereon and configured to slide over an cylindrical base in an embossing or casting assembly. The substrate is a flat web, foil, or film of, for example, paper, polyester, polypropylene, metal or other elongated flat material. The surface relief can be applied through interfering ablation, non-interfering ablation, ink jet printing, or other techniques wherein a seamless surface relief is formed onto the seamless sleeve. A method of making a seamless, embossed or cast substrate includes expanding a diameter of a seamless sleeve having a seamless surface relief formed thereon, sliding the expanded seamless sleeve onto a cylindrical base, allowing the diameter of the seamless sleeve to contract around the cylindrical base, and conveying a substrate through the embossing or casting assembly and embossing or casting the seamless surface relief into the substrate.

While a wide variety of aromatic ester repeating units may be employed, the polymer is nevertheless “low naphthenic” to the extent that it contains a minimal content of repeating units derived from naphthenic hydroxycarboxylic acids and naphthenic dicarboxylic acids. Despite the absence of a high level of conventional naphthenic acid repeating units, the present inventors have discovered that selective control over the type and relative concentration of the biphenyl repeating units can lead to “low naphthenic” polymers that are not only soluble in certain solvents, but also capable of exhibiting good mechanical properties. Thus, the ability of the resulting polymer to be dissolved or dispersed in various solvents can be enhanced without sacrificing performance.

    Abstract: Polymers and copolymers containing 1H-benzo[d]imidazol-2(3H)-one units have been synthesized under conditions generally used for the synthesis of poly(aryl ether)s. 1H- benzo[d]imidazol-2(3H)-one behaves like a biphenol in the polymerization reaction. The soluble homopolymer has a very high glass transition temperature (348° C.), good thermal stability, and forms flexible transparent films. Because of the low molecular weight (134.14) of the benzoimidazolone monomer in the copolymer formed with 4,4?-biphenol that contains 30 mole % of the benzimidazolone unit, only 8.9 weight % is required to raise the Tg of the poly(arlyl ether)sulfone from 220° C. to 269° C.

  • Publication number: 20130085251
    Abstract: Polymers and copolymers containing 1H-benzo[d]imidazol-2(3H)-one units have been synthesized under conditions generally used for the synthesis of poly(aryl ether)s. 1H- benzo[d]imidazol-2(3H)-one behaves like a biphenol in the polymerization reaction. The soluble homopolymer has a very high glass transition temperature (348° C.), good thermal stability, and forms flexible transparent films. Because of the low molecular weight (134.14) of the benzoimidazolone monomer in the copolymer formed with 4,4?-biphenol that contains 30 mole % of the benzimidazolone unit, only 8.9 weight % is required to raise the Tg of the poly(arlyl ether)sulfone from 220° C. to 269° C.

  • Patent number: RE43880
    Abstract: This invention relates to the composition and a solvent-free process for preparing novel imide oligomers and polymers specifically formulated with effective amounts of a dianhydride such as 2,3,3?,4-biphenyltetra carboxylic dianydride (a-BPDA), at least one aromatic diamine and an endcapped of 4-phenylethynylphthalic anhydride (PEPA) or nadic anhydride to produce imide oligomers that possess a low-melt viscosity of 1-60 poise at 260-280° C. When the imide oligomer melt is cured at about 371° C. in a press or autoclave under 100-500 psi, the melt resulted in a thermoset polyimide having a glass transition temperature (Tg) equal to and above 310° C. A novel feature of this process is that the monomers; namely the dianhydrides, diamines and the endcaps, are melt processable to form imide oligomers at temperatures ranging between 232-280° C. (450-535° F.) without any solvent.
