Description
Technical field
The invention belongs to aromatic diamine and preparation method thereof and polyimide or polymeric amide technical field, be specifically related to the aromatic diamine and preparation method thereof of phthalonitrile pendant group and by the aromatic diamine of phthalonitrile structure phthalonitrile pendant group polyimide or polymeric amide as the monomer preparation.
Background technology
Polyimide (PI) is the high-performance polymer that one type of main chain contains imide ring; Because it has excellent thermostability, mechanical property, unreactiveness, dielectric properties and radiation resistance, has obtained widespread use with commercial form such as film, coating, fiber, plastics, tackiness agent and polymer matrix composites in high-tech sectors such as aerospace, electronic industries already.Polyimide utilizes aromatic dianhydride and diamines through the polycondensation preparation, and its building-up process is as follows:
Aromatic series dianhydride aromatic diamine aromatic polyimide
Polyimide mainly can be divided into non-crosslinked property polyimide and Thermocurable polyimide.Compare with non-crosslinked property polyimide, Thermocurable polyimide has good processibility, and can keep polyimide excellent comprehensive performance relatively.At present, researching and developing more Thermocurable polyimide is to contain acetylene group (U.S.Pat.No.4,098; 767) and the polyimide of phenylacetylene group (U.S.Pat.No.5,412,066); The polyimide that contains acetylene group, overlapping because of the melt temperature of the temperature of reaction of acetylene group and imide oligomer thing, make its processing temperature window very narrow; Thereby limited its application in casting heavy wall or complicated shape composite product, and contained the polyimide of phenylacetylene group, because the curing exotherm of phenylacetylene group wherein is fast; And poor controllability; Make the heavy wall composite product of making cause its thermal gradient excessive easily, cause unrelieved stress, make material present fragility and easy to crack.In addition, need at the anhydrous and oxygen-free conditional operation owing to prepare the triphenyl phosphorus/palladium ligand catalyst that uses in the polyimide of acetylene END CAPPED GROUP and phenylacetylene-capped base, thereby preparation condition is harsh, cost is very high, has limited the degree of depth and the range of its application.
Solidifying the phthalocyanine resin that is obtained by phthalonitrile-terminated verivate is another kind of high performance material with excellent mechanical behavior under high temperature.Though the cross-linking and curing reaction of phthalonitrile is controlled, can be applicable to the processing request of different composite material, and the resin after solidifying have excellent thermal property and mechanical property (Keller T.M.PolymerComposites; 2004,25,554); But because of the research of the phthalocyanine modified polyimide of reports such as Keller mainly concentrates on phthalonitrile-terminated type polyimide (Keller T.M.Polymer, 1993,34; 952.Keller T.M.Polymer Communications, 1991,32; 2), its structure is as follows:
And also there is following problem in phthalonitrile-terminated type polyimide:
(1) because the phthalonitrile unit is in the polymkeric substance end of the chain, and its reactive behavior is subject to the molecular weight of polymkeric substance, molecular weight is too big; The phthalonitrile reactive behavior reduces, and is difficult to form effectively crosslinked (U.S.Pat.No.5,132; 396); Molecular weight is too small, and the cross-linking density of polymkeric substance is excessive again, with making polymkeric substance present bigger fragility.
(2) existing phthalonitrile-terminated type polyimide, its molecular weight are usually all in the 2000g/mol scope, so its film-forming properties is relatively poor, has limited its application in film material and fiber art.
Similar with polyimide, also be one type of high-performance polymer by aromatic series diacid chloride and diamines through the aromatic polyamide that polycondensation prepares, it is synthetic as follows with general structure:
Aromatic series diacid chloride aromatic diamine aromatic polyamide
Because traditional common infusibility indissoluble of aromatic polyamide is difficult to processing, thereby people have studied a lot of modified methods to improve the processibility of polymeric amide.These modified methods mainly are included on the main chain of polymeric amide and introduce side group (Meyer.M.R.Macromolecules; 24; 642) be processibility though these means can significantly improve the organic soluble of polymeric amide,, because the reduction of polyimide molecule chain rigidity; Thereby sacrificed excellent thermal property, mechanical property and the solvent resistance of polymeric amide, limited the range of application of polymeric amide.
