the CO2 solubility in PP/talc composite滑石粉s without interfa
373.15 and 393.15 K respectively and pressure range of 0~16 MPa.Compared with the solubility of CO2 in pure PP， but smaller at higher pressure. Solubility of CO2 in interface modified PP/talc composites is less than that in pure PP and PP/talc composites without interface modification. Diffusion coefficient of CO2 in PP/talc composites is smaller than that in pure PP and decreases with the increase of talcum content.Solubility of CO2 in amorphous region of pure PP and interface modified PP/talc composites were correlated with the Sanchez-Lacombe state equation in conjunction with the interaction parameters. The swelling degree of polymer matrix caused by CO2 was also predicted，滑石粉， the CO2 solubility in PP/talc composites without interface modification is larger at lower pressure， polypropylene/talcum (talc) composites and interface modified PP/talc composites at temperatures 343.15， Gravimetric method was adopted to measure solubility and diffusivity of CO2 in pure polypropylene (PP)， which could prove the filler hinderance for the movement of polymer chains. 。
