The unsaturated polyester obtained in this way has a structure and a molecular weight as shown below, even if it has the same composition as a low molecular weight unsaturated polyester resin, it has a molecular weight of 3000 or less. This is based on the discovery that it has significantly superior physical properties compared to low molecular weight unsaturated polyester resins.
