Background technology
High-molecular polymer alloy material refers to the multicomponent system consisting of two or more macromolecular material, belongs to alloy material.Physics blend, the block copolymerization in multipolymer and the graft copolymers etc. of different polymkeric substance all belong to polymer alloy category (envelope Piao, < < polymer alloy > >, Shanghai Tongji University press, 1997; Tao Jianying, technology status and the development prospect of engineering plastics based polymer alloy, Shanghai chemical industry, 2003,02).
Polythioetherimide, because thioether bond flexible unit is incorporated in the polyimide main chain of rigidity, this base polymer is except having outstanding thermomechanical property, also having that solvability is good, melt viscosity is low and the feature of melt-processable, is a kind of very promising thermoplasticity high temperature polymeric materials.For example, publication number is that CN101463132A, CN101392055A, CN101531758A, CN101704950A and application number are the excellent over-all propertieies such as in 200910153055.5 Chinese patent application, disclosed multiple Polythioetherimide all has good heat resistance, toughness is high, melt viscosity is low, and cost is relatively low, in association areas such as resistant to elevated temperatures engineering plastics, film, sizing agent, enameled wire, porous plastics, fiber and advanced composite materials, there is good application prospect.
Compare with poly arylidene thio-ester, polyimide exists that processing forming is poor, not alkali corrosion resistance, the shortcoming such as expensive; And poly arylidene thio-ester has excellent chemical resistance, at 200 ℃, be substantially insoluble to below any solvent, good mechanical property, relatively low cost and the good advantages such as moulding processability, but its fragility is large, poor toughness, resistance to impact shock are low.Owing to all there being a large amount of aromatic nucleus on the molecular chain of polyimide and poly arylidene thio-ester, structural similarity makes them have good consistency, the processing temperature of polyimide and poly arylidene thio-ester matches simultaneously, all 300 ℃ of above processing, therefore by poly arylidene thio-ester modified polyimide, improve its processing forming and reduce costs, having caused that people pay close attention to greatly.For example, in US Patent No. 4455410 (application of General Electric company), a kind of polyetherimide/polyphenylene sulfide alloy material is disclosed, article the preparation method of polyphenylene sulfide modified polyetherimide.The sign > > of document < < polyphenylene sulfide, polysulfones and polyetherimide binary and tertiary blending system (Polymer Engineering and Science, 1991,32 (2): the blended modifier that 84-91) discloses polyphenylene sulfide and polyetherimide, blend is incompatible system, and the tensile strength of blend declines with the increase of polyphenylene sulfide content.A kind of polyimide/polyphenylene sulfide alloy material is disclosed in US Patent No. 4017555, the polyimide of not melting is carried out to modification by the blend with polyphenylene sulfide, when the content of polyphenylene sulfide reaches 40%, alloy material has obtained good machine-shaping property and good fluidity of molten, but, on the one hand because the consistency of this polyimide and polyphenylene sulfide is poor, and polyphenylene sulfide is more crisp, cause the mechanical property of polyimide to damage larger, the polyimide raw material price used is on the other hand more expensive, make the cost value of polyimide/poly arylidene thio-ester alloy material of preparation higher.

In order to characterize the fluidity of molten of Polythioetherimide and polyphenylene sulfide alloy, in BrabenderPlasticorder Mixer instrument, carry out the test of torque-proportion relation.
By equal Polythioetherimide (ii), polyphenylene sulfide is respectively by the ratio of following different weight percent: 100/0, 80/20, 70/30, 60/40, 50/50, 40/60, 30/70, 20/80 weighing, be pre-mixed respectively 2h, the material mixing is joined and in Brabender torque rheometer, carries out melt blending, wherein the test conditions of melt blending is: blending temperature is 330 ℃, rotor speed is 30 revs/min, until moment of torsion reaches balance, test period is about 15 minutes, measure the torque rheology of Polythioetherimide and polyphenylene sulfide alloy, test result is in Table 1:
The alloy torque of table 1 Polythioetherimide/polyphenylene sulfide and proportion relation
| Equal Polythioetherimide/polyphenylene sulfide | Torque (N.m) | Polythioetherimide/polyphenylene sulfide | Torque (N.m) |
| 100/0 | 21.3 | 50/50 | 5.1 |

As can be seen from Table 2, in Polythioetherimide and polyphenylene sulfide alloy material, when Polythioetherimide is matrix, alloy material mechanical property is than the not too large variation of pure Polythioetherimide.But, when the content of polyphenylene sulfide surpasses 50% in alloy material, the mechanical property of alloy has declined much with respect to pure Polythioetherimide, this is because the mechanical property of alloy material is mainly reflected on matrix, therefore when polyphenylene sulfide is matrix, mechanical property, especially impact strength decreased a lot.
