Mushtaq, Nafeesa; Chen, Guofei; Sidra, Lala Rukh; Zhang, Anjiang; Fang, Xingzhong published the artcile< Kinetic Studies of Bischloroimide Monomers for the Facile Synthesis of Different Molecular Architecture Poly(phthalimide-co-naphthalimide)s>, Recommanded Product: 5-Chloroisobenzofuran-1,3-dione, the main research area is polyphthalimide naphthalimide bischloroimide kinetics thermal mech property.
A series of different mol. architecture (homo, random, block and gradient type) copolymers PI-3(a-e) were synthesized by solution polycondensation. Three different bischloroimide monomers [bischlorophthalimide 2a, bischloronaphthalimide 2b and bischloro (naphthalimide-phthalimide) 2c] were prepared and reacted with 4,4′-thiobisbenzenethiol by different synthetic routes. The chem. reactivity of these monomers 2(a-c) was examined by kinetic study of model compounds N-phenyl-4-chloro-1,8-naphthalimide and N-phenyl-4-chlorophthalimide using gas chromatog. mass spectrometry (GC-MS). The difference in chem. reactivity of monomers was utilized to design mol. architecture of copolymer, and the influence of comonomers sequence on copolymer properties is investigated. The synthesized copolyimides PI-3(a-e) integrated the excellent properties of naphthalimide and phthalimide as good organosoly., high glass transition temperature of 198-319°C and good thermooxidative stability based on 5% weight loss temperature of 492-524°C and 480-532°C in nitrogen and air, resp. Gradient type sequence PI-3 e offers a good combination of phthalimide and naphthalimide groups in copolymers for improved thermal and mech. properties.
