Polyesters having a saturated backbone, methods for preparing the polyesters, intermediate unsaturated polyester products, and methods for preparing the intermediate unsaturated polyester products are disclosed. Here, the number of main chain carbon atoms between two adjacent ester groups in the main chain is randomly distributed across the polyester, the polyester having an M / E ratio of 14 or more, In the formula, M is the number of main chain carbon atoms in the polyester not containing ester carbon, and E is the number of ester groups in the polyester. |
