摘要

Solid phase transition of the a form crystals to the β form crystals in syndiotactic polystyrene (sPS) samples hasoccurred in supercritical CO2. This transformation is different from those detected under other conditions. The effects ofsome factors (e.g time

temperature

and pressure) on the solid phase transformation of sPS in supercritical CO2 wereanalyzed in detail. Experimental results show that longer time

higher temperature or higher pressure favors the transformation of the α form crystals to the β form crystals.
