This study reports the synthesis of polyurethaneยฑimide (PUยฑimide) copolymers using 4,4'diphenylmethane diisocyanate (MDI) polytetramethylene glycols (PTMGs) and different aromatic dianhydrides. Differential scanning calorimetry (DSC) results indicate that PUยฑimide copolymers had two phase structures

A new approach to obtain imide-containing elastic polymers (IEPs) via elastic and high-molecular-weight polyureas, which were prepared from โฃ-(4-aminobenzoyl)--[(4-aminobenzoyl)oxy]-poly(oxytetramethylene) and the conventional diisocyanates such as tolylene-2,4-diisocyanate(2,4-TDI), tolylene-2,6-di
## Abstract Different multiple hard segment polyurethaneโimide copolymers (MHPUI) were synthesized and characterized. FTIR spectroscopy confirmed the characteristic absorption of the MHPUI copolymer. The difference in the imide group FTIR absorption bands in different MH segment PUI copolymers was
Novel type of mesogenic chain extenders used in this study are N,Nะ-bis(4hydroxyphenyl)-3,4,3ะ,4ะ-biphenyldicarboxyimide (BPDI) and N, Nะ-bis[4-(6-hydroxyhexyloxy) phenyl]-3,4,3ะ,4ะ-biphenyldicarboxyimide (BHDI). BHDI has a flexible spacer of 6-methylene units but BPDI does not. The liquid crystalli
