Table 4
By table 4 it will be evident that the glass transition temperature of 1-6 of the embodiment of the present invention is significantly lower than comparative example, show this hair
Bright lower temperature resistance is preferable.The constituent part of Comparative Examples 1-5 is different from embodiment 2,5, wherein Comparative Examples 2,3,5
Glass transition temperature has different degrees of rising, illustrates that PUA, PUD, ionic liquid can effectively improve lower temperature resistance；Reference is implemented
The glass transition temperature and embodiment 1-6 of example 1,4 are similar, illustrate that cosolvent, dispersing agent have little effect lower temperature resistance.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology all without departing from the spirit and scope of the present invention, carries out modifications and changes to above-described embodiment.Cause
This, institute is complete without departing from the spirit and technical ideas disclosed in the present invention by those of ordinary skill in the art such as
At all equivalent modifications or change, should be covered by the claims of the present invention.
