Notes:
Summary Films of amorphous syndiotactic polystyrene were exposed to dichloromethane vapour at varying activity, up to a=1. Infrared analysis and wide angle X-ray scattering were used to follow the development of ordered structures, induced by the vapour. It has been found that characteristic bands in the infrared spectrum appear after activity a=0.45, whereas X-rays show that the sample is still amorphous. The appearance of the crystalline reflections occurs at higher activities and a continuous improvement up to a=1 in the X-ray pattern is observed.
