Abstract
The present invention provides a method for preparing high molecular polyesteramide, which comprises: diacid diester which is obtained by the reaction of aromatic dibasic anhydride and monobasic alcohol is acetylized and chlorinated in a solvent with a high melting point; the solid solution of diester and diacid chloride is formed by lowering temperature; the solution of the aprotic polar solvent of the diacid chloride and diamine existing in the form of the solid solution carries out condensation and polymerization reaction between liquid-solid two phases between-5 and-10 DEG C.
Description
The invention belongs to the preparation method of high-molecular polyamide ester.
Polyesteramide (PAE) is a kind of important as precursors (precursor) form of polyimide (PI).(PAA) compares with polyamic acid, and PAE can prepare the more solution of high solids content, and better stability in storage is arranged, and when imidization, molecule interchain imidization do not take place generally.With the PAE solution of flexible chain and the PAE solution blending of stiff chain, during imidization, intermolecular commentaries on classics amidation (transamidation) can not take place, can form flexible chain PI on the molecular level and the matrix material of stiff chain PI well, and improve the performance of two kinds of PI; Another important application of PAE is ester type photosensitive polyimide (ester-type PSPI), ester-type PSPI storge quality is good, solid content is high, be easy to form thick glued membrane, not only be widely used in the microelectronics manufacturing, and be used in the micromechanics manufacturing, forming miniature electroforming mould, is one of very important high-performance photoetching glue.
PAE synthetic generally is the esterification, chloride by dianhydride and finishes with three steps of diamines polycondensation.The preparation side that Chinese patent 97105274.3 discloses a kind of ester type photosensitive polyimide is sent out, and this method is carried out the liquid liquld interfacial polycondensation reaction by the diamines of diester diacid chloride in the organic phase and aqueous phase, obtains polyesteramide.But the water-soluble diamines that can be used as the polycondensation raw material is very limited, and commonly used have only mphenylenediamine and Ursol D, limited the use of this method; Pukun Zhu et al. is published in journal of applied (J of Applied Polymer Science, Vol.55:1111 (1995)) " poly-imido preparation of silica of negative light-sensitive and the characteristic " paper on has been described the solution polycondensation reaction method in a kind of three steps an of still, because the reaction between diacid chloride and the diamines is too fierce, or because hydrolysis reaction easily takes place in diacid chloride, or owing to the diacid chloride monomer is difficult for being purified, during batching, difficulty is accomplished two kinds of mol ratios such as monomeric, make that obtained product PAE molecular weight is very low, the polymer property viscosity of weighing molecular weight standard is lower than 0.16dL/g.Though also some method can be used for synthesizing PAE, is not that the limitation problem is arranged, and is exactly unfavorable factors such as synthetic cost height.For example use dicyclohexyl carbodiimide (DCC), diphenyl (2,3-dihydro-2-thioxo-3-benzoxazo-lyl) condensing agent of phosphonate (DDTBP) and so on makes two acid diesters and diamines be condensed into its limiting viscosity of PAE and generally is no more than 0.65dL/g, and condensing agent is too expensive, should not be used for producing.
The preparation method who the purpose of this invention is to provide a kind of high-molecular polyamide ester.This method is come the PAE of synthetic macromolecule amount by controls reaction speed, inhibition hydrolytic side reactions and " adjusting automatically " function of reaction monomers proportioning.
The object of the present invention is achieved like this, active diester diacid chloride monomer is dispersed in the solvent (as tetramethylene sulfone) of higher melt, form solid solution at low temperatures, as this diester diacid chloride that exists with the solid solution form and the N of diamines, N-N,N-DIMETHYLACETAMIDE (DMAc) Gu or the solution of other aprotic polar solvent carry out liquid--during the reaction of-two alternate solution polycondensations, reaction be along with solid solution in DMAc dissolving gradually and carry out gradually, the active high component of control enters the speed of reactive system effectively, and slows down speed and inhibition hydrolytic side reactions that reaction is carried out; On the other hand, because diacid chloride progresses into reaction system, and once entering reaction system, just complete with diamine reactant at once.Therefore, in the reaction system for some time two kinds monomericly be near the equivalent than regular meeting, promptly regulate monomeric proportioning automatically.So can obtain the high-molecular weight product.
The present invention adopts following component synthesizing polyamides ester.

The solvent that uses among the present invention is:
(1) high-melting-point solvent: tetramethylene sulfone or sym-trimethylbenzene
(2) aprotic polar solvent: N,N-dimethylacetamide, N, dinethylformamide, N-
N-methyl-2-2-pyrrolidone N-, HMPA
The chlorine hydride absorbent of using among the present invention is: pyridine and triethylamine
Concrete synthesis step is as follows:
Aromatic dianhydride and monohydroxy-alcohol are added in dystectic solvent by one to two molar weight,, obtain the solution of the high-melting-point solvent of two acid diesters 50--65 ℃ of reaction 6-12 hour; In this solution, dripping an amount of SOCl under 10--25 ℃
2After, keep under this temperature and reacted 2-3.5 hour, and at room temperature remove hydrogenchloride and form waste gas of sulfur dioxide and the superfluous SOCl that remains in the system with two hours high vacuum
2, the solution of the high-melting-point solvent of acquisition diester diacid chloride; Cool the temperature to below-15 ℃, make this solution solidifies, obtain to contain the solid solution of diester diacid chloride; To be added on the above-mentioned solid solution with the DMAc solution of the diamines of dianhydride equal molar quantities, keep-5--10 ℃ between stirring reaction 2-3 hour, go out product with ethanol, water precipitation, the limiting viscosity of gained polyesteramide is at 0.60-1.42dL/g.
Because the present invention has adopted the diester diacid chloride that reactive behavior is strong to be dispersed into solid solution, the polycondensation of diacid chloride and diamines is occurred between their liquid, the solid two phase liquid, and carry out gradually with the progressively dissolving of solid solution, controlled the fierce degree of reaction effectively and paid reaction, obtained high-molecular weight PAE with the hydrolysis that has suppressed diacid chloride.When more particularly two acid diesters or diester diacid chloride are difficult for separation and purification, adopt this method, carry out the polycondensation in three steps an of still, more demonstrate its advantage, the limiting viscosity of product P AE is generally at 0.6-1.42dL/g.
