Liu, Jiangtao; Chen, Guofei; Fang, Xingzhong published the artcile< Synthesis and characterization of high performance poly(thioether imide)s via aromatic nucleophilic substitution reaction of isomeric AB-type monomers>, HPLC of Formula: 118-45-6, the main research area is polyimide polythioether synthesis property.
A series of isomeric poly(thioether imide)s (PTIs) containing thioether linkages were prepared by aromatic nucleophilic substitution reaction of isomeric N-(4-mercaptophenyl)-3-chlorophthalimide and/or N-(4-mercaptophenyl)-4-chlorophthalimide. The inherent viscosities of these polymers were in the range of 0.38-0.42 dL/g. The glass transition temperature increased with increasing the content of 3-substituted phthalimide unit in the polymer backbone. The 5 % weight loss temperatures of isomeric PTIs (a-e) were 506-531° in nitrogen and 509-536° in air, resp. The isomeric PTIs (b-d) films exhibited good mech. properties with tensile strength of about 90 MPa, elongation at break of more than 6.0 %, and tensile moduli of more than 2.2 GPa. The storage moduli of PTIs (b-d) almost completely maintained at about 2.0 GPa before reaching the corresponding glass transition temperatures It is noted that the min. melt viscosity of these polymers decreased with increasing the content of unsym. 3- and 4-substituted phthalimide unit.
Polymer Bulletin (Heidelberg, Germany) published new progress about Elongation at break. 118-45-6 belongs to class chlorides-buliding-blocks, and the molecular formula is C8H3ClO3, HPLC of Formula: 118-45-6.
