Epitaxial crystallization of isotactic poly(methyl methacrylate) on highly oriented polymers
Article Abstract:
The annealing behavior of amorphous isotactic poly(methyl methacryalte)(i-PMMA) thin films on highly oriented high-density polyethylene (HDPE) substrates was studied by transmission infrared spectroscopy and electron diffraction. The i-PMMA thin film on highly oriented HDPE exhibits a much faster crystallization rate than usual, providing not only a good method for the preparation of crystalline i-PMMA thin and ultrathin film, but also the convenience to observe the crystallization process by infrared spectroscopy in situ.

Initial crystallization mechanism of isotactic polystyrene from different states
Article Abstract:
The isothermal crystallization processes of isotactic polystyrene at 160 degree Celsius from different initial states, that is, cold- and melt-crystallization processes are investigated by infrared (IR) and generalized two-dimensional IR correlation spectroscopy. It is concluded that the physical origins for spinodal decomposition prior to polymer crystallization may be different for different crystallization processes.

Spin-coated polyethylene films probed by single molecules
Article Abstract:
Ultrathin spin-coated high-density polyethylene films by means of single-molecule spectroscopy and microscopy at 1.8 K is studied. Results reveal a preferential orientation of dopant molecules along two well-defined, mutually perpendicular directions.
