    • 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 μm and about 30 μm 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.
    • 稳定的高性能聚合物组合物,包括聚苯并咪唑(PBI)和三聚氰胺 - 甲醛聚合物,例如甲基化,聚(三聚氰胺 - 共 - 甲醛),用于形成诸如膜,纤维和大体积结构的结构。 聚合物组合物可以通过将聚苯并咪唑与三聚氰胺 - 甲醛聚合物组合以形成前体而形成。 聚苯并咪唑可以与三聚氰胺 - 甲醛聚合物反应和/或缠结形成聚合物组合物。 例如,可以由聚合物组合物形成具有例如约5μm至约30μm的厚度的稳定的自立膜。 这样的膜可以用作气体分离膜,并且可以长时间浸入水中而不会龟裂和破裂。 聚合物组合物也可以用作基底上的涂层,例如金属和陶瓷,或者可以用于纺丝纤维。 还公开了用于形成这种聚合物组合物的前体。

    • An environmental friendly poly(ether-fattyamide) coating composition for mild steel plates or the like comprises and/or consists of a condensation polymerization product of a fatty diol and an aromatic/cyclic diol and wherein the fattyamide diol is synthesized using rapeseed oil and further cured with an aminoplast resin and a catalyst. The rapeseed oil is combined with a crosslinker such as hexa methoxy melamine formaldehyde, butylated melamine formaldehyde, urea formaldehyde of hydroxyl values of 220-240 mg KOH/gm of resin and curing catalysts. The curing catalyst may be para toluene sulphonic acids, dodecyl sulphonic acids, orthro phosphoric acid in a solvent such as xylene, ethyl methyl ketone, ethylene glycol mono methyl ether and aromatic hydrocarbons. Additional agents such as surfactants, stabilizers, wetting agents, flow modifiers, dispersing agents, adhesion promoters and UV absorbers may be added.

    • Provided is a precoated fin material for heat exchangers that allows the construction of a fin structure in which frost formation at the time of heater operation can be prevented to the extent possible, and under such a condition that condensation is liable to occur on a fin surface, a water droplet of condensed water can be quickly removed by bringing the water droplet into contact with a hydrophilic film, and as a result, a favorable heat exchange function can be maintained without any increase in ventilation resistance. Also provided is a heat exchanger including such fin structure. The precoated fin material for heat exchangers includes: a fin substrate formed of an aluminum plate material; a crosslinked hydrophobic film having a frost formation-suppressing effect, the crosslinked hydrophobic film being formed on one surface of the fin substrate and being formed of an aqueous hydrophobic coating composition containing a resin (A) having a fluorine atom-containing group, a quaternary ammonium salt group-containing modified epoxy resin (B), and an amino resin (C) at predetermined ratios; and a hydrophilic film having a condensed water-removing effect, the hydrophilic film being formed on another surface of the fin substrate. The heat exchanger includes a fin structure in which a hydrophobic surface having a frost formation-suppressing effect and a hydrophilic surface having a condensed water-removing effect are opposite to each other.
