Abstract
The present invention provides a thermally decomposable binder that achieves a reduced residual carbon after sintering, and that can be subjected to a dewaxing treatment at a relatively low temperature in a non-oxidative atmosphere. More specifically, the present invention provides an aliphatic polycarbonate that has a structure obtained by neutralizing a Brønsted acid with an organic onium salt in a side chain.
