Polyester solid phase polymerization catalyst for low acetaldehyde generating resins |
| abstract |
This invention discloses a process for producing a polyester resin having a low acetaldehyde generation rate comprised of the steps of polycondensing the polyester resin in the presence of tin and antimony; wherein the tin is present within the range of 50 to 110 ppm of the polyester resin and the antimony is present from 105 ppm to 265 ppm of the polyester resin, and solid phase polymerizing the polyester resin for sufficient time so as to increase the intrinsic viscosity of the polyester resin by at least 0.15 dl/g. |
