  • Patent number: 10351660
    Abstract: A phenolic resin composition and an epoxy resin composition from which a cured epoxy resin having excellent heat resisting properties and a low dielectric constant can be produced. The phenolic resin composition contains a modified phenolic resin and a tetrakisphenolethane compound, the modified phenolic resin being prepared by condensation of a cyclic hydrocarbon compound having two or more unsaturated bonds and a compound having a phenolic hydroxyl group, in which the content of the tetrakisphenolethane compound is 3% to 60% by mass with respect to the total content of the modified phenolic resin and the tetrakisphenolethane compound. The epoxy resin composition is prepared by epoxidizing the phenolic resin composition. The cured epoxy resin is prepared by allowing the epoxy resin composition to react with a hardener.

    Abstract: Stable, high performance polymer compositions including polybenzimidazole (PBI) and a melamine-formaldehyde polymer, such as methylated, poly(melamine-co-formaldehyde), for forming structures such as films, fibers and bulky structures. The polymer compositions may be formed by combining polybenzimidazole with the melamine-formaldehyde polymer to form a precursor. The polybenzimidazole may be reacted and/or intertwined with the melamine-formaldehyde polymer to form the polymer composition. For example, a stable, free-standing film having a thickness of, for example, between about 5 ?m and about 30 ?m may be formed from the polymer composition. Such films may be used as gas separation membranes and may be submerged into water for extended periods without crazing and cracking. The polymer composition may also be used as a coating on substrates, such as metal and ceramics, or may be used for spinning fibers. Precursors for forming such polymer compositions are also disclosed.

In one embodiment the plastics consist of patterned mixtures of poly(phthalaldehyde) polymers in which each polymer contains a different end-capping group (also called a “trigger”), responsive to a different signal. Other embodiments use different polymers and different triggers. The plastics may be homogeneous in composition, but each polymer within the plastic is capable of responding to a different signal and depolymerizing once this signal reacts with the trigger. This process of depolymerization enables the plastic to alter its physical features non-linearly to external signals: i.e., the degree of change in physical form is much larger than the intensity of the initial signal.

  • Publication number: 20120129976
    Abstract: Processes of making articles of a melt mixed polyoxymethylene composition comprising polyoxymethylene polymer and polyoxymethylene terpolymer in which the melt mixed composition is maintained above the crystallization temperature of the polyoxymethylene polymer. Such processes impart improved creep resistance compared to that of articles made of the same melt mixed composition but which has been cooled below crystallization temperature of the polyoxymethylene polymer during manufacture. These articles are useful for making plastic gears having high heat resistance.

  • Patent number: 8133933
    Abstract: Phenolic resin binder systems for sand molds, used in metal casting, which improve the quality of thermally reclaimed sand, are described. The substantial or complete elimination of calcium compounds (e.g., calcium stearate and calcium hydroxide, conventionally employed as a mold lubricant and a resin curing catalyst, respectively) allows the thermally reclaimed sand to be reused over multiple thermal reclamation cycles without the adverse effects previously encountered.
