A new homologous series of linear aliphatic polyesters, such as poly (cis-2-
butenylene carboxylate)S, PBms (m is the number of methylene groups in the acid
component, m=2-8 have been synthesized by direct polyesterification reactions in
anisole, as solvent. FT-IR, 400 MHz H- NMR, C-NMR and elemental
analysis were used to establish the structure of polyesters. Molecular weight
distributions were studied by GPC. The most narrow distributions were found to
be for PB2 and PB8, whereas, the average molecular weight for all polyesters,
except PB6, was about 3000-400
