Three monomers were prepared from 4,4-bis(4′-hydroxyphenyl)valeric acid (BHVA) namely its methylester (BHVAM), its bis-acetylated methylester (BAVAM) and its 4,4-bis(4′-acetoxyphenyl)valeric acid (BAVA). All three monomers were polycondensed in bulk at various temperature profiles using Ti(OBu) 4 , Co(OAc) 2 , Mn(OAc) 2 , Sn(OAc) 2 or Bu 2 Sn(OAc) 2 ...
