| Abstract: | The preparation of a new unsaturated polyester(UP), the cost of which is 500 Yuan/t lower than that of common UP, from PET waste by catalytic alcoholysis and esterifying condensation is described in this paper. The molecular weight of the UP is 1900-2300, acid number is 19-29 and storage stability is 8 months. |
