    Synthesis and thermal properties of polyamide 6 (A)-polyimide (B) block copolymers of ABA type

    Polyimides (PI) having different molecular weights were prepared by condensation of oxydiphthalic anhydride with 9,9-bis-(4-aminophenyl)fluorene in nitrobenzene solution at 180°C. These polyimides carried two ...

    (RS)-, (R)- and (S)-3-benzyl-3-ethyl 2-oxetanone polymerization with chiral and achiral initiators

    The polymerization of 3-benzyl-3-ethyl 2-oxetanones leads to three types of polymers: polyRS (enantiomer excess,ee=0), polyR or polyS (Ree >See) and polyracemate. All these polymers are crystalline and the therma...
