The MDSC results show that high energy ball milling is capable of forcing the mixing of TD and SL at a molecular level, providing a homogeneous amorphous solid solution. The glass transition temperatures (T g ), determined for the comilled formulations, range from 79°C to 139°C and they are higher than T g of pure SL (ca. 70°C) and lower than T g of pure TD (ca. 149°C).
