含二氮杂萘酮结构新型聚酰亚胺的合成
Synthesis of Novel Polyimides Containing Phthalazinone Moiety
摘要
Abstract
Three diamine monomers containing phthalazinone moiety have been synthesized, and then a novel type of un-symmetrical polyimides were prepared from these diamines and 4, 4'-(4,4'-isopropylidenediphenoxy)bis(phthalic anhydride) (BPADA). The structure of the polymers were characterized by FTIR and 1H NMR, the properties of them were investigated by DSC, TGA and GPC, and the solubility and inherent viscosities were also investigated. The results indicated that the polymers were easily soluble in aprotic polar organic solvents such as chloroform, pyridine, DMF, DMAc and NMP at room temerature, and the chloroform solution of these polymers could be cast into transparent and flexible films. The inherent viscosities of the polymers were in the range of 0. 50~0. 81 dL·g-1. The number average molecular weight(Mn) and polydispersity index(PDI) of polymers (P4b~P4c) were in the range of 25 000~34 000 and 1. 21~1. 27, respectively. Moreover, the glass transition temperature(ig) of the polymers were all above 235 'C and the residual weight were in the range of 51% ~ 58% at 800℃ in nitrogea The 5% and 10% weight loss temperatures of these polymers were in the range of 446~480℃ and 459～495℃ , respectively.关键词
