摘要：

A novel crosslinkable diacetylene-polyimide was prepared from 4,4'-(1,3-butadiyne-1,4-diyl)-bis(phthalic anhydride) and p-phenylenediamine in order to develop a high temperature material with multidimensional high modulus. The polyimide crosslinked thermally about 250-degrees-C. The extent of crosslinking was 85%. The storage modulus of the resulting crosslinked polyimide was about twice larger than that of non-crosslinked polyimides. The plateau storage modulus of the crosslinked polyimide increased with increasing temperature as a result of crosslinkage of the diacetylene groups till higher temperatures than that of polyimides without diacetylene groups.
