Porous poly(trimethylene carbonate) structures can readily be prepared using high pressure CO2. Differences in CO2 solubility in the polymer matrix at the different processing temperatures and pressures lead to different pore morphologies upon depressurization. Furthermore, crystallization of the initially amorphous polymer leads to stable porous structures. This variation in pore structure can be used to tailor polymer matrix degradation rates and drug release profiles
