摘要： A graft copolymer having a polyolefinic main chain with muconic acid groups pendant therefrom. The acid groups are bonded to the backbone of the polyolefin by free radical addition across a muconic acid double bond. Preferably, the copolymer is prepared via a reactive extrusion process. The copolymer's applications include use as a reactive compatibilizer for polymer blends. The preferred polyolefin is polypropylene.

摘要： A compatible polymer blend containing a polyacetal, a hydroxylated polyacetal, polypropylene, and an acid-grafted polyolefine such as a muconic acid-polypropylene graft copolymer. The polyacetal is preferably a polyoxymethylene polymer such as Celcon.RTM.. The preferred hydroxylated polyacetal is one having a structure very similar to the polyacetal. The invention also includes a process for forming a compatible blend containing polypropylene and polyacetal by melt mixing polypropylene and polyacetal with an acid grafted polyolefin and hydroxylated polyacetal.

摘要： This invention discloses novel membranes comprised of a blend of polyarylate and polybenzimidazole polymers. A membrane prepared from the blend of polybenzimidazole and polyarylate polymers exhibits enhanced properties over membranes prepared solely from either a polyarylate or a polybenzimidazole polymer. The addition of the polyarylate to the polybenzimidazole membrane allows the composition to be more thermally processable and less susceptible to moisture. The presence of the polybenzimidazole renders the polyarylate less reactive to solvents and increases its thermal stability. In addition, it has been surprisingly found that membranes prepared from the polybenzimidazole polyarylate blends show high regeneration capacity while retaining good flux ranges. The membranes prepared by this process exhibit good separation characteristics and provide an improved membrane with enhanced qualities over prior art membranes.
摘要翻译：本发明公开了由多芳基化合物和聚苯并咪唑聚合物的共混物组成的新型膜。由聚苯并咪唑和聚芳酯聚合物的共混物制备的膜在仅由多芳基化合物或聚苯并咪唑聚合物制备的膜上表现出增强的性能。将多芳基化合物加入到聚苯并咪唑膜中可使组合物具有更好的热可加工性，并且不易受潮气影响。聚苯并咪唑的存在使多芳基化合物对溶剂的反应性降低，并增加其热稳定性。此外，已经令人惊奇地发现，由聚苯并咪唑多芳基化合物共混物制备的膜显示出高再生能力，同时保持良好的通量范围。通过该方法制备的膜显示出良好的分离特性，并提供与现有技术膜相比具有增强质量的改进的膜。

摘要： A miscible blend comprising from about 5 to about 95 weight percent of a polybenzimidazole and from about 95 to about 5 weight percent of a polyamide-imide having fluorine-containing linking groups, total weight percent of the two polymers being 100. A process for preparing the blends comprises dissolving in a mutual solvent from about 5 to about 95 weight percent of the aromatic polybenzimidazole to about 95 to about 5 weight percent of the polyamide-imide having fluorine-containing linking groups, based on the total weight of those polymers and subsequently evaporating the solvent, thereby producing a dried blend of a polybenzimidazole and a polyamide-imide having fluorine-containing linking groups. The blends, particularly in the form of films, fibers or fibrets, may be post-treated with heat or sulfuric acid in order to minimize their shrinkage when subsequently subjected to heat and in order to increase their resistance to solvents and acid. The polyamide-imides having fluorine-containing linking groups are prepared by forming the polycondensation product of one or more aromatic diamines, one or more trifunctional acid anhydride monomers, and one or more tetrafunctional aromatic dianhydrides, at least one of said monomers containing the group ##STR1## linking two aromatic moieties, wherein R is CF.sub.3 or phenyl.

摘要： A novel miscible composition comprising from about 5 parts by weight to about 95 parts by weight of a polyarylate and from about 95 parts by weight to about 5 parts by weight of an aromatic polybenzimidazole. In a composition mostly comprised of an aromatic polybenzimidazole, it is preferred that the polyarylate be present in the composition in an amount sufficient to make the aromatic polybenzimidazole more thermally processable and also less susceptible to moisture. More preferably, such compositions are comprised of from about 60 parts by weight to about 95 parts by weight of an aromatic poloybenzimidazole and from about 40 parts by weight to about 5 parts by weight of a polyarylate. Most preferably, such compositions are comprised of at least about 10 parts by weight of a polyacrylate. In a composition mostly comprised of a polyarylate, it is preferred that the aromatic polybenzimidazole be present in an amount sufficient to render the polyarylate less sensitive to solvents, and to increase the thermal stability of the polyarylate. Preferably, the aromatic polybenzimidazole is present in such compositions in an amount sufficient to result in a composition with greatly enhanced solvent resistance. More preferably, such compositions are comprised of from about 60 parts by weight to about 95 parts by weight of a polyarylate and from about 40 parts by weight to about 5 parts by weight of an aromatic polybenzimidazole. Most preferably, such compositions should contain at least about 25 to about 30 parts by weight of a polybenzimidazole in order to render the polyarylate component much more resistant to solvents at room temperature. In addition to improving solvent resistance, greater amounts of aromatic polybenzimidazole in the composition substantially increase the thermal and physical properties of the composition, giving excellent price-performance characteristics. The compositions, particularly in the form of films or fibers, may be post-treated with heat or sulfuric acid in order to minimize their shrinkage when subsequently subjected to heat and in order to increase their resistance to solvents and acid.

摘要： The present invention provides novel heat stable polyamide-imide polymers having excellent flow properties and moisture stability which render them more readily processible into fibers, films, sheets and other molded articles. The polymers are prepared by forming the polycondensation product of one or more aromatic diamines, one or more tetrafunctional aromatic dianhydrides, and a difunctional aromatic carboxylic acid or amide-forming derivative thereof containing the groups ##STR1## linking two aromatic moieties, wherein R is CF.sub.3 or phenyl. In addition to improved flow properties, the polyamide-imide polymers of this invention also exhibit improved solubility properties in most organic solvents, improved resistance to attack by chlorinated solvents such as trichloroethylene as compared with polyimides, improved hydrophobic properties as well as excellent thermal properties, including resistance to thermooxidative degradation.
