A poly(amide-imide) copolymer including an amide structural unit having an amide bond in a polymer main chain and an imide structural unit having an imide bond in a polymer main chain, wherein at least one imide structural unit includes a moiety cross-linked to an adjacent polymer main chain through an amide bond.

The invention discloses a method for manufacturing a new sound-absorbing and noise-reducing material by using polyimide foam scraps, cutting and processing the scraps generated in the process of polyimide foam production into particles of different sizes, drying red iron oxide or black iron oxide or titanium dioxide as inorganic additive, and then using each component in parts by weight, putting the inorganic additive into the mixer, and then putting the polyimide foam particles of different sizes into the mixer to mix, injecting the curing agent into the mixer to continue mixing, and finally adding the catalyst into the mixer to continue mixing, putting the mixed material into the mold evenly to form the film, leaving it for 10 hours, opening the mold, taking out the product, removing the burrs, and cutting the product according to customer needs, and packing it in a carton for storage.

A poly(amide-imide) copolymer including an amide structural unit having an amide bond in a polymer main chain and an imide structural unit having an imide bond in a polymer main chain, wherein at least one imide structural unit includes a moiety cross-linked to an adjacent polymer main chain through an amide bond.

A poly(amide-imide) copolymer including an amide structural unit having an amide bond in a polymer main chain and an imide structural unit having an imide bond in a polymer main chain, wherein at least one imide structural unit includes a moiety cross-linked to an adjacent polymer main chain through an amide bond.

This invention pertains to high selectivity poly(imide-urethane) membrane and a method of making the same. This invention also pertains to applications of the high selectivity poly(imide-urethane) membranes not only for a variety of gas separations such as separations of carbon dioxide/methane, hydrogen/methane, helium/methane, oxygen/nitrogen, carbon dioxide/nitrogen, olefin/paraffin, iso/normal paraffins, xylenes, polar molecules such as water, hydrogen sulfide and ammonia/mixtures with methane, nitrogen, or hydrogen and other light gases separations, but also for liquid separations such as pervaporation and desalination.

A polyurethane dispersant is described that comprises a reaction product of a polyisocyanate with a) a component supplying a anchoring imide group wherein the carbonyl groups of the imide are bonded to a fused or non-fused aromatic ring, b) at least one solvent-solubilizing chain, and other optional components to build molecular weight or modify the interaction of the dispersant with various particulates or continuous media.
