    摘要： Polyimide of this invention is almost colorless and has remarkably high light transmittance as well as excellent processability and adhesive properties at high temperatures in addition to its substantial high-temperature stability. The polyimide is a novel polyimide capable of being used for space and aeronautical materials, electric and electronic members, automotive parts, and furthermore for high-temperature adhesives. The polyimide has recurring units of the following formula (I):
    wherein X is a radical selected from the group consisting of a bond, divalent hydrocarbon radical having from 1 to 10 carbons, hexafluorinated isopropylidene radical, carbonyl radical, sulfonyl radical and thio radical, and each nitrogen atom of imide ring is located simultaneously at meta- or para-position to ether linkage. The polyimide of this invention is prepared by reacting 4,4ʹ-(p-phenylenedioxy)diphthalic dianhydride with an ether diamine having the following general formula (V):
    and successively imidizing the resultant polyamic acid.

    摘要： A process for preparing a polyimide by reaction of a diamine and a tetracarboxylic dianhydride to obtain a polyamide acid and subjecting the polyamide acid to conversion into a polyimide thermally or chemically. The reaction in the process is carried out in the presence of at least one dicarboxylic anhydride selected from the group consisting of aliphatic dicarboxylic anhydrides and aromatic dicarboxylic anhydrides, and the amount of the tetracarboxylic dianhydride is in the range of from 0.9 to 1.0 mole per mole of the diamine and the amount of the dicarboxylic anhydride is in the range of from 0.001 to 1.0 mole per mole of the diamine. The resultant polyimides exhibit good thermal stability at high temperatures and good forming processability even at low temperatures.

    摘要： This invention relates to a method for preparing polyimide having good heat-stability and excellent flowability in a molten state.
    The polymide is prepared by reacting aromatic diamines such as 4,4′-bis(3-aminophenoxy)biphenyl, bis[4-(3-aminophenoxy)phenyl] ketone and bis [4-(3-aminophenoxy)phenyl] sulfone; tetracarboxylic dianhydrides such as pyromellitic dianhydride, 3,3′,4,4′-benzophenonetetracarboxylic dianhydride and bis(3,4-dicarboxyphenyl) ether dianhydride; and monoamines such as n-hexylamine, cyclohexylamine, aniline, 4-aminobenzophenone. The molar ratio of tetracarboxylic dianhydride : aromatic diamine : monoamine is 1:(0.9 to 1.0):(0.001 to 1.0).
    Another invention relates to polyimide composite materials which are excellent in mechanical strengths and processability. The materials contain the polyimide above prepared and fibrous reinforcing materials such as yarn, roving, tow, fabrics, mats and felts of glass fiber, carbon fibers or aromatic polyamide fibers.
