Description
Technical field
The invention belongs to field of organic polymer compound, and in particular to a kind of polyamideimide resin containing indane structural
And preparation method thereof.
Background technology
Aromatics Thermocurable polyimide (PI) resin is due to wide with excellent heat endurance and mechanical behavior under high temperature
It is general to be applied to every field.But the solubility in organic solvent of the imide resin after imidization is far below technological requirement, institute
With more than when prepreg is prepared, hot setting is molded in the form of amic acid, but resin can be produced during hot imidization
The small molecule product such as water, the problems such as cause the porosity of product high, making the processing of large scale product becomes difficult, and this is also to cause
The reason for limited one of polyimides application is extremely important.Therefore, it is solvable fusible and with excellent processability after exploitation imidization
The polyimides of energy increasingly attracts attention[1-2].Polyamide-imides (PAI) is regarded as polyimides and aromatic series polyamides
The alternate copolymer of amine, belongs to the transformed lines show of polyimides.Polyamide-imides molecular backbone is by two kinds of acid amides and acid imide
Construction unit is constituted, thus with heat resistance as polyimide, while its dissolubility and machinability are improved,
It is a kind of resin with excellent machinability[3-4]。

The viscosity of performed polymer PAI1-4 is as the curve of temperature change is as shown in fig. 7, the viscosity of performed polymer shows
First reduced as temperature is raised, a period of time is then kept at a relatively low viscosity, finally drastically elevated trend.Curve
The specific data of gained are listed in table 2.Understand, with the increase of molecular weight, the minimum melting viscosity increase that performed polymer shows
(PAI1, PAI2, PAI3 change to 7.1 again to 52.4Pa s from 1.2), keep narrowing compared with the land regions of low-viscosity (PAI1,
PAI2, PAI3 change to 60 DEG C from 128 DEG C again to 17 DEG C), process window narrows explanation performed polymer as molecular weight increases, molecule
Chain movement reduced capability;And the viscosity of performed polymer starts drastically elevated temperature spot and is more or less the same, at 320 DEG C or so, this master

DEG C/min carries out thermal weight loss test in the range of 50~800 DEG C.
Result is as shown in Figure 8.Four kinds of PAI are respectively provided with preferable heat endurance, but are still below polyimides, and this is due to dividing
Backbone portion contains aliphatic structure in son.After solidification resin in air atmosphere 5% weightless temperature (T5%) at 480 DEG C
Left and right, this explanation T5% with crosslink density relation less, and depends primarily on the power of key.But for T10%, number of repeat unit
N=3,6 are better than n=1,2, and this is probably the volatile small molecule that molecular weight high is produced due to when temperature is less high
It is less.
The present invention introduces " circle " shape structure in the molecular structure, reduces the accumulation compactness of strand, is conducive to solvent
The infiltration of molecule, so as to increase the dissolubility of resin.This " circle " shape structure refers to that one of atom is connected on main chain

By Fig. 9 it can be seen that, the glass of polyamide-imide resin PAI-1 (upper figure) after solidification and PAI-2 (figure below)
Change transition temperature up to more than 330 DEG C, this is due to containing the ring in certain rigid structure and indane in trimellitic anhydride
Shape structure increased the glass transition temperature that both steric hindrances of sub-chain motion effectively improve resin.Simultaneously can from figure
Know that the crosslink density of polymer declines as the increase molecular weight of number of repeat unit increases, turn the vitrifying after resin solidification
Temperature is gradually reduced.
