Abstract

The morphological evolution of poly(butylene succinate) (PBS) solution‐grown single crystals during annealing was studied using hot‐stage atomic force microscopy. Their morphology changed with increasing temperature and annealing time. The annealing behavior and melting temperature were found to be affected by the substrate. Morphological changes occurred at a much lower temperature on an amorphous carbon film than that on a mica surface. Moreover, the pattern of morphological evolution of the single crystals on a carbon film was different from that on a mica surface. Since the PBS melt had a larger contact angle on the mica surface, these differences in the melting behavior were ascribed to the different interfacial interactions between the chain‐folded surface of the single crystal and the substrate.

## Abstract **Summary:** Poly(butylene succinate) (PBS) and PBS‐based ionomers (PBSi's) with 0.3 and 1.2 mol‐% of sodium sulfonated succinate unit were synthesized. The existence of ionic aggregates in the ionomer matrices was indicated by melt viscosity and glass transition data. It seems that the

## Abstract Crystallization behavior was investigated for poly(butylene succinate)‐based ionomers (PBSIs) with very small amounts of metal sulfosuccinate units. The PBSI samples, precipitated by adding their chloroform solutions into an excess volume of hexane, showed not only higher overall crysta

Annealing in air produces less photocurrent and a small IPC/IDC ratio compared t o those of unannealed CdS : Yb crystals. Annealing in sulfur makes the crystals very conducting without any increase due t o photoexcitation. Annealing in presence of Cd metal makes the photo-response quite fast. Result
