RENEWABLE POLYESTER COMPOSITIONS THAT HAVE LOW DENSITY. |
| abstract |
A thermoplastic composition is provided that contains a rigid renewable polyester and has a porous structure and low density. To achieve such a structure, the renewable polyester is mixed with a polymeric hardening additive to form a precursor material in which the hardening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. The precursor material, after that, lengthens or stretches at a temperature below the glass transition temperature of the polyester (ie, "cold drawn"). This creates a network of cavities that are adjacent to the discrete domains that As a result of their proximal location, they can form a bridge between the boundaries of the cavities and act as internal structural "hinges" that help stabilize the network and increase their capacity to dissipate energy. The present inventors also discovered that the cavities can be distributed in a way practically homogeneous throughout the composition. |
